Abstract

PURPOSE:To effectively execute a check job by using a conditional interruption generating instruction generating only the necessary instruction and passing it simply when not required. CONSTITUTION:In inserting a condition interruption generating instruction is inserted, an instruction discrimination section 1 recognizes it to send a bit of interruption generation condition information (a) generated by both the state selection field in the instruction and the condition field is sent to a condition storage section 2. The condition storage section 2 sends a bit of information (b) specifying the location in the information (a) to an information selection section 3 and the interrupt generation designation condition (c) is transferred to a comparison evaluation section 4. The information selection section 3 extracts the present status of the location according to the received location specific information (b) and sends it to the comparison evaluation section 4 as a bit of state information (d), the comparison evaluation section 4 compares and evaluates the designation condition (c) and the state information (d) in parallel, and when the condition is coincident, a bit interruption signal (e) is generated. Thus, the check efficiency is improved.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides an information processing system that enables an interrupt to be generated only when the state of a specified part inside a device matches a specified condition. FJ!
Regarding equipment.

(Prior art) When creating and realizing a processing procedure system for executing various processes using an information processing device, at the inspection stage, it is necessary to investigate the processing execution status at each point in time to ensure that the system operates as designed. There are many occasions when it is necessary to check whether the

Conventionally, when the need for such an investigation arises, an interrupt generation command is inserted to generate an interrupt state in the device, and then various surrounding conditions are investigated.

However, once an interrupt generation instruction is inserted, it will always generate an interrupt every time the corresponding processing step is reached, and it will be executed even when it is not needed, making the corresponding operation complicated and requiring extra time. As a result, inspection efficiency could be adversely affected.

For example, in a processing procedure that is repeated 100 times, 10
In order to investigate the state at the time of the 0th execution, 99 meaningless interrupts must be performed and all the corresponding operations must be performed, which is an unavoidable hassle and waste of time. There was a problem.

(Problems to be Solved by the Invention) As described above, the interrupt generation command in conventional information processing devices always generates an interrupt even when it is not needed, forcing unnecessary operations and time consumption. It contained problems.

In view of these problems, the present invention provides a conditional interrupt generation instruction that generates a duplicate interrupt when necessary, and simply passes through when unnecessary, thereby improving inspection work. The purpose is to enable more effective implementation.

[Structure of the invention]

(Means for Solving the Problem) In order to achieve such an objective, the present invention provides a conditional interrupt that inspects the state of a specified part inside the device and prompts an interrupt to occur when specified conditions are met. an instruction discriminator capable of recognizing the generated instruction; a condition holding section that holds the condition specified by the conditional interrupt generation instruction; and a condition holding section that selects the internal state of the device corresponding to the specified condition and stores the information. The apparatus comprises: an information selection section that transfers the information, and a comparison and evaluation section that compares and evaluates the information and the specification section f] and generates an interrupt if the information matches the specification section f. It is now possible to generate an interrupt only when the state of a specified internal part meets specified conditions.

(Function) If the information processing device has such a configuration, it is possible to specify the parts to be compared and evaluated in advance and generate an interrupt using a conditional interrupt generation instruction that sets the condition value. By inserting it between processing steps, it is possible to generate an interrupt only in the specific situation where it is needed, allowing for investigation at that point, and to simply pass through when it is unnecessary, that is, when the specified conditions are not met. This enables continuous execution of subsequent processing procedures, eliminates redundant interrupt operations and meaningless time consumption, and enables efficient actual IA of inspection work.

(Embodiment) FIG. 1 shows a schematic block diagram of a conditional interrupt generation instruction for an information processing apparatus as an embodiment to which the present invention is applied.

Reference numeral 1 indicates an instruction determination unit capable of recognizing a conditional interrupt generation instruction; 2 indicates a condition holding unit that retains the interrupt condition; 3 indicates an information selection unit that selects state information of a specified portion; and 4 indicates the condition and the This is a comparison and evaluation section that compares and evaluates the selection information and generates an interrupt signal e if there is a match.

In addition, a is interrupt generation condition information extracted from the instruction discriminator,
b is information specifying the part, C is interrupt generation specification condition, and d is status information of the specified part.

Further, FIG. 2 shows the configuration format of a conditional interrupt generation instruction in one embodiment. The instruction consists of three fields, each representing an instruction code field 11, a state selection field 12, and a condition field 13.

Next, the operation will be described. While processing procedures are sequentially retrieved from a storage unit (not shown) that stores a processing procedure system and executed, if a conditional interrupt generation instruction is inserted, the instruction determination unit 1 Recognizing this, the interrupt generation condition information a generated by both the condition fff1mff1m field and the condition field 13 in the instruction is sent to the condition holding section 2. The condition holding section 2 sends the information specifying the part in the information a to the information selection section 3, and also transfers the interrupt generation specification condition C to the comparison evaluation section 4. The information selection section 3 extracts the current state of the corresponding region according to the received region specifying information d, and sends it to the comparison evaluation section 4 as state information d. The comparison and evaluation section 4 compares and evaluates the specified condition C and the state information d side by side, and when the conditions match, an interrupt signal e' is generated.
4! : Occurs, otherwise the execution of the - processing procedure instructions is terminated, and the instruction discriminator 1 is instructed to extract the next processing procedure.

In this way, it is possible to generate an interrupt only when the state of the specified portion matches the interrupt generation designation conditions, and to continue executing the subsequent processing procedure when the conditions do not match.

〔Effect of the invention〕

As explained above, in the information processing device to which the present invention is applied, it is possible to add a comparative evaluation condition regarding the state of a specific part to the interrupt generation command to select whether or not to interrupt. By eliminating the occurrence of unnecessary interrupts, it is possible to improve inspection efficiency by eliminating wasteful response operations and meaningless time consumption caused by unnecessary interrupts in the inspection process when creating and realizing a processing procedure system. become able to.
