Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a method for reading video stream data according to an embodiment of the present invention is shown, where the method may include:
s11: and receiving a data processing request, and determining video stream data which corresponds to the data processing request and needs to be processed as target data.
It should be noted that, the execution subject of the video stream data reading method provided by the embodiment of the present invention may be a corresponding video stream data reading apparatus. The video stream data can be stored in the memory RAM, and further read from the memory RAM when the video stream data needs to be processed. It should be noted that the video stream data is continuously stored in the memory RAM, and thus the video stream data has continuous addresses. After receiving the data processing request, the video stream data target data which needs to be processed in the RAM can be determined, and then the target data is read and processed.
S12: and if the data bit of the target data is larger than the data bit which can be read by a single read port, judging whether a parallel read mark is set, if so, reading the target data in a parallel mode by using a plurality of read ports, and if not, reading for multiple times by using the single read port until all the target data are read.
Since the data bits that can be read by a single read port are fixed, such as 8 bits; however, the data bit length of the video stream data required when the video stream data is processed is not fixed, so in the present application, the data bit of the target data determined when the target data is determined is an integer multiple of the data bit that can be read by a single read port, specifically, the data bit that needs to be processed may be rounded up by dividing the data bit that needs to be processed by the data bit that can be read by a single read port, and then the data bit of the target data may be obtained by multiplying the result of rounding up by the data bit that can be read by a single read port, and then the corresponding target data may be determined from the memory RAM. It should be noted that, in this embodiment, it is first determined whether a data bit of target data is larger than a data bit that can be read by a single read port, and if the determination result is yes, it is determined that the target data cannot be read by the single read port at one time, at this time, it is necessary to determine whether the current scene has high requirements on data reading efficiency and data processing efficiency of video stream data, that is, whether parallel read marks are provided, if so, multiple portions included in the target data are read in parallel by using multiple read ports, and if single data read is used as one read cycle, multiple sets of data can be read in one read cycle in a parallel read manner in this application, so that the data reading efficiency is greatly improved, and the data processing efficiency is further improved; if not, the current scenario is indicated to have low requirements on data reading efficiency and data processing efficiency, or the reading port needs to be utilized to read other data, so that a single reading port is directly utilized to read all the target data for multiple times. Therefore, the method can flexibly realize the quick reading or normal reading of the target data based on the requirements of the current scene on the data reading efficiency and the data processing efficiency.
In addition, the data volume of the read ports can be set according to actual needs, for example, the read ports can be two groups of independent read ports; each read port is independent and has a clock (clk _ r), a read enable signal (r _ en), a read address (r _ addr), and a read data output (r _ data _ out) pin. In the application, the read enable signal can be controlled to realize data reading in a mode of inputting the read enable signal to the read port.
S13: and if the data bits of the target data are not larger than the data bits which can be read by the single read port, directly reading the target data by using the single read port.
If the data bits of the target data are not larger than the data that can be read by a single read port, the target data can be read directly by the single read port.
According to the technical scheme, when the data bit of the target data needing to be read is larger than the data bit which can be read by a single read port, if the parallel read mark is arranged, the requirement of the current scene on the data reading efficiency and the data processing efficiency is high, different parts in the target data are read in parallel by using a plurality of read ports, so that the data reading efficiency is greatly improved, and the data processing efficiency is further improved. And when the data bit of the target data to be read is larger than the data bit which can be read by a single read port, if the parallel read mark is not set, the data reading efficiency and the data processing requirement of the current scene are low or the read port is required to be used for reading other data, the target data can be read for many times by the single port, so that the requirements of different scenes can be met.
The method for reading video stream data according to the embodiment of the present invention may further include, after determining that video stream data that needs to be processed currently and corresponds to the read enable signal is target data:
judging whether a check mark is set or not, if so, simultaneously executing the step of reading the target data by utilizing a plurality of reading ports so as to read and obtain a plurality of copies of the target data; if the read target data are all the same, determining that the verification is passed, and determining that the read target data are video stream data needing to be processed; if the read target data of the multiple copies are not all the same, determining that the verification fails;
and if the check mark is not set, directly executing the step of reading the target data to read a copy of the target data.
In order to ensure the validity of the read data, the read target data may be verified in this embodiment, specifically, multiple sets of target data may be read simultaneously by using the above method, and then it is determined whether the read target data are the same, if so, it indicates that the read ports are normal, and therefore, the data is verified to be passed, otherwise, it indicates that an abnormal condition exists, and the data is not verified to be passed. Moreover, the check mark is not required to be set in the scene with lower requirement on the data validity, so that the requirements of different application scenes can be flexibly met in the mode. In addition, in this embodiment, the manner of reading the multiple sets of target data or the single set of target data is implemented according to steps S12 to S13, which is not described herein again.
The method for reading video stream data provided by the embodiment of the present invention may further include, after determining that the verification fails:
if at least two identical target data exist in the read multiple target data sets, determining that the at least two identical target data sets are video stream data needing to be processed, and outputting port marks of read ports corresponding to target data different from the video stream data needing to be processed in the read multiple target data sets.
Because the read port can read correct data only when no abnormality exists, and the possibility that the read same data is the same is extremely low if the abnormality exists in the plurality of read ports, in this embodiment, if the read target data are not all the same, it is determined whether at least two identical target data exist therein, and if so, it is determined that the at least two identical target data are correct target data, that is, video stream data to be processed; and then, outputting port marks of the read ports corresponding to other target data different from the correct target data, so that a worker can timely know the read ports which are possibly abnormal based on the port marks, and further realize corresponding repair operation and the like.
The method for reading video stream data provided by the embodiment of the present invention may further include, after determining that the verification fails:
and if any two identical target data do not exist in the read multiple target data, outputting a read mark of a read port for reading the multiple target data and a module mark of the storage module where the multiple target data are located before being read.
If any two identical target data do not exist in the read target data, correct target data cannot be determined, and the read port with the abnormality cannot be preliminarily judged, so that in this case, the port marks of all the read ports are all output, so that a worker can timely know the read port with the abnormality on the basis, and further corresponding repair operation and the like are realized; in addition, the storage module is a module for storing video stream data, such as a memory RAM, and in this embodiment, in order to avoid an abnormality caused by the storage module, a module flag of the storage module is also output, so that a worker performs operations such as detection and repair on the corresponding storage module based on the module flag.
The method for reading video stream data provided in the embodiment of the present invention may further include, after determining the video stream data that needs to be processed:
determining the data bit of the video stream data needing to be processed currently as a target data bit;
if the data bit of the video stream data needing to be processed is larger than the target data bit, the data of the target data bit is taken from the video stream data needing to be processed for processing, and redundant data is cached for the next processing.
It should be noted that, because the data bits of the target data determined when the target data is determined are integer multiples of the data bits that can be read by a single read port, specifically, when the target data is read, the data bits that need to be processed may be divided by the data bits that can be read by a single read port, and rounded up, and then the result obtained by rounding up is multiplied by the data bits that can be read by a single read port to obtain the data bits of the target data, so as to determine the corresponding target data from the memory RAM. Therefore, the data bits of the data which may be read and needs to be processed are larger than the data bits which can be currently processed, only the data of the data bits which can be currently processed are taken for processing, and the rest data are cached (for example, cached in a register) and taken out for use when the video stream data needs to be processed next time; specifically, when the video stream data needs to be processed next time, if the data bit of the buffered video stream data is the data bit of the data which needs to be processed currently, the video stream data is directly taken out and processed, if the data bit of the buffered video stream data is smaller than the data bit of the data which needs to be processed currently, the video stream data is continuously read, the data bit of the buffered data plus the data bit of the read part or all of the video stream data is equal to the data bit of the data which needs to be processed currently, then the buffered data and the read whole or part of the video stream data are processed together, if the data bit of the buffered video stream data is larger than the data bit of the data which needs to be processed currently, the video stream data of the data bit of the data which needs to be processed currently is taken out from the buffered video stream data and processed, and the residual data in the buffer is processed next time, and so on; therefore, the repeated acquisition of the same data is avoided, and the data reading resource is saved. In addition, if the data bit of the video stream data needing to be processed is equal to the target data bit, directly taking the video stream data needing to be processed for processing, if the data bit of the video stream data needing to be processed is smaller than the target data bit, continuously reading the sum of the data bit of the video stream data needing to be processed and the data bit of all or part of the read video stream data to be equal to the data bit of the data needing to be processed currently, and then processing the video stream data needing to be processed and all or part of the read video stream; that is, in this application, when processing is performed each time, if the data bit of the read data (the read data includes data in the cache and/or data read at the current time) is smaller than the data bit of the data that needs to be processed currently, the data is continuously read to obtain the data of the data bit of the data that needs to be processed currently, if the data bit of the read data is larger than the data bit of the data that needs to be processed currently, the data of the data bit of the data that needs to be processed currently is taken to be processed, the data of the redundant data bit is left to be processed next time, and if the data bit of the read data is equal to the data bit of the data that needs to be processed currently, the read data is directly processed.
Before reading target data in a parallel manner by using a plurality of read ports, the method for reading video stream data according to the embodiment of the present invention may further include:
dividing target data into a plurality of data parts, and setting a serial number corresponding to the address of each data part; wherein the data bits of each data portion are equal to the data bits that can be read by a single read port;
reading the target data in a parallel manner using a plurality of read ports may include:
reading a plurality of data parts corresponding to target data in a parallel mode by utilizing a plurality of reading ports in a one-to-one correspondence mode of the reading ports and the data parts;
after the target data is read in a parallel manner by using a plurality of read ports, the method may further include:
and splicing the read data parts according to the serial numbers of the data parts to obtain target data.
It should be noted that, in this embodiment, corresponding sequence numbers may be set according to addresses of data portions divided for the target data, so that the position where the data portion should be located in the target data can be determined according to the sequence numbers of the data portions, and after a plurality of data portions of the target data are read, the data portions are spliced into the target data according to the sequence numbers of the data portions, thereby facilitating parallel reading of the target data.

Therefore, the technical characteristics disclosed by the application can read multiple groups of data by utilizing multiple reading ports in one reading period, so that the data reading efficiency and the data processing efficiency are improved.
