Definitions

  • the present invention generally relates to an electronic circuit for managing the operation of a watch having several functions. These functions are performed by different devices, each of these devices being controlled by a controller.
  • the electronic circuit comprises a processor connected to a non-volatile memory that contains instructions to be made, peripheral controllers for interacting with watch peripherals, and connection means arranged to allow peripheral controllers to the non-volatile memory and the processor communicating information relating to the operation of said watch, with each other.
  • the electronic circuits for managing this watch, that is to say for example to count the seconds, to rotate the hands or to manage the manual action of the user on the buttons of said watch.
  • the electronic circuits according to the prior art comprise a processor associated with a non-volatile memory storing program lines necessary for the operation of the watch, as well as peripheral controllers. These device controllers are responsible for making the connection between the devices of the watch such as the motor / needle assembly, the chain of division or others.
  • connection means for the transfer of information are arranged so that all communications pass through said processor.
  • each watch circuit is specifically wired according to the functions it has. This entails significant inventory risks of electronic watch circuits in the event that they have not had the expected success.
  • the invention relates to an electronic watch circuit which overcomes the aforementioned drawbacks of the prior art, namely large consumptions and a lack of flexibility, said circuit being intended to execute operations independently of the processor and / or the memory nonvolatile.
  • the invention relates to an electronic circuit for managing the operation of a watch cited above, which is characterized in that further includes initialization means that can act on the device controllers to initialize them and enable them to perform operations independently of the processor and / or the nonvolatile memory.
  • An advantage of the circuit according to the invention is that an initialization means is able to act on the peripheral controllers to initialize them and enable them to execute operations independently of the processor and / or the non-volatile memory. This ensures that on the one hand, it is possible for the peripherals to be autonomous with respect to the processor with or without the non-volatile memory without closing the door to a reintegration of said processor in the management of the operation of the watch. On the other hand, this allows a reduction of the power consumption which would go from 7.6 ⁇ A during a management according to the prior art to a consumption of the order of 400nA in the case of management according to the present invention.
  • Another advantage of the present invention is to guarantee a flexibility of the electronic watch circuit so that according to the present invention, the number of applications in the circuit is not fixed. This allows a series of manufacturing to another, less worry about inventory problems since the circuit is flexible enough to implement applications other than the original ones and therefore use this circuit in many products.
  • the present invention also relates to a method for initializing an electronic watch circuit so that the latter can be managed without the processor and the non-volatile memory where the code lines coding the applications are stored, are put into operation. .
  • this method is characterized in that an access to the initialization means is performed, then a reading of the data therein is made for then executed which allows the initialization of the controllers of peripherals.
  • a particular step of the process is the subject of the dependent claim 12.
  • the figure 1 schematically represents the electronic watch circuit 1 according to the present invention.
  • This circuit 1 manages the operation of a watch and comprises in the same chip, a processor 2 communicating with a non-volatile memory 3, peripheral controllers 4 communicating outside the electronic circuit 1 with the peripherals of the watch and communicating with the receiver.
  • internal circuit itself via connecting means 6a, 6b and 7.
  • These connecting means 6a, 6b and 7 allow peripheral controllers to communicate with each other but also with the processor 2 and therefore also with the non-volatile memory 3.
  • the electronic circuit 1 is powered by a voltage source, typically a battery, whose voltage is preferably 1.55V although a voltage other than this may be used. Of course, other power supply means are possible.
  • a voltage source typically a battery, whose voltage is preferably 1.55V although a voltage other than this may be used.
  • other power supply means are possible.
  • the technology used for it may be a nonvolatile memory technology 3 allowing the realization of a nonvolatile memory 3 of Flash or EEPROM type.
  • These non-volatile memories 3 allow rewriting of the data in the case of partial or total reprogramming according to the evolution of the electronic watch circuit 1 in time.
  • nonvolatile memories can be used.
  • the choice of one type of memory compared to another is based on characteristics of size, capacity, power consumption see access performance and reading of each type of memory considered.
  • This non-volatile memory 3 is intended to contain lines of codes of the instructions used for the operation of the watch. These instructions can be divided into two categories: standard instructions and specific instructions. Standard instructions are those instructions of the watch that are most commonly used or that are permanently integrated into electronic watch systems. For example, instructions for incrementing the time, displaying the time, the date or even the stopwatch functions. Conversely, specific instructions are those instructions which are not necessary for the proper functioning of the watch or which are not all the time implanted in watches such as the instructions for managing a transceiver, instructions for use. external sensor controls, meteorological function management instructions, etc. Preferably, it is arranged for the non-volatile memory 3 to be consists of two distinct areas: a first where the standard instructions are written and a second where the specific instructions are written.
  • peripheral designation is given for the systems of the watch which are useful for the operation of said watch and the realization of the functions that the latter proposes.
  • the quartz accompanied by its division chain for timing the different elements.
  • the present circuit 1 comprises a single oscillator for clocking all the elements of the watch.
  • Other devices may be the motor systems of the hands or the display screen depending on whether it is an analog watch or digital.
  • the inputs / outputs that is to say the different buttons of the watch
  • optional peripherals can be the engine systems of a stopwatch or the management systems of any function using a sensor. like a compass or altimeter or whatever.
  • Each device is thus connected to a peripheral controller 4 located in said electronic watch circuit 1.
  • controllers each include an initialization register 5 for setting certain internal data to each peripheral such as, for example, the characteristics of the driving pulses: frequency , length or other in the case of the device controller of the driving pulse generator.
  • the different elements of the electronic circuit 1 are connected to each other via the connecting means 6a, 6b and 7. These are represented on the figure 1 partly by 2 multiplexers 6a and 6b. These multiplexers 6a and 6b are called initialization multiplexer 6a for the one which serves above all to allow initialization of the initialization registers 5 of the peripheral controllers 4, and the operating multiplexer 6b, for the one which serves for its part. allow the flow of data between the different elements when the circuit 1 is in normal operation.
  • the two multiplexers 6a and 6b are connected to the different elements by communication buses 7.
  • the processor 2 which is also capable of communicating with the 4. This is because the circuit 1 may optionally be independent of processor 2 and nonvolatile memory 3. It will also be pointed out that other connection means 6a, 6b and 7 may be used in the electronic watch circuit 1 according to the present invention.
  • the present circuit 1 differs from what is currently known by the presence of an initialization means 8 for configuring the peripheral controllers 4 and the connecting means 6a, 6b and 7 that is say the multiplexers 6a and 6b, so that the peripherals can operate completely independently of the processor 2 and the non-volatile memory 3.
  • This initialization means 8 is represented on the figure 1 as a programmable memory 8 containing the initialization data to be implemented in the initialization registers 5 of the peripheral controllers 4 and the initialization data of the connecting means 6a and 6b.
  • This programmable memory 8 is connected to the initialization registers 5 of the peripheral controllers 4 via the initialization multiplexer 6a and a communication bus 7.
  • This initialization means 8, the peripheral controllers 4 and the connection means 6a, 6b and 7 form the autonomous assembly 9 used for the watch to operate without intervention of the processor 2 and the non-volatile memory 3.
  • the initialization instructions that are set in the boot registers 5 of the peripheral controllers 4 are the following data. As data implanted in the various initialization registers, we first find the specific characteristics of the devices such as those mentioned before, these not contributing to the decrease in the power consumption of circuit 1, that is to say, not contributing to make the peripherals autonomous. The problem is solved by the implementation of instructions configuring the inputs / outputs of each device controller 4.
  • each device controller 4 has a series of inputs / outputs allowing it on the one hand to communicate with the device that corresponds to it, that is to say to receive information from the latter and other part to communicate with the processor 2, that is to say to transmit information to the processor 2 and to receive the data of the latter to be transmitted to the device.
  • the processor 2 that is to say to transmit information to the processor 2 and to receive the data of the latter to be transmitted to the device.
  • the processor 2 will process this information that is to say, interpret what this change of state means and act accordingly, that is to say execute the instruction that manages the stopwatch and transmit it to the corresponding peripherals, namely the hands and engine of the stopwatch as well as the clock.
  • the present invention differs from the prior art in that, in the case of the example above, the change of state of the actuated button variable will be sent directly to the peripherals so that they can fulfill their purpose. function.
  • the processor 2 which on the one hand, allows us to save time of cycles and on the other hand, allows us to gain in consumption since n There is no need to turn on processor 2 to perform these tasks.
  • the electronic watch circuit 1 had the possibility of using the processor 2 in order to execute specific instructions. But it should be noted that the processor 2 can also be turned on to execute standard instructions if necessary. Therefore, we will explain below the process so that the processor 2 is used for the purpose of executing these instructions.
  • the processor 2 must be able to be reset at any time as soon as an instruction that it is specific or standard, must be executed by said processor 2. For this, it is expected that each device can be able to send an interruption signal via the connection means 6a, 6b and 7 to the processor 2.
  • This interrupt signal enables the operation of the processor 2 so that to execute the instructions stored in the nonvolatile memory 3. To do this, the interrupt signal, once received by the processor 2, will trigger the awakening of the latter, which will then go from a passive mode to a active mode where he can perform tasks.
  • the processor 2 will access the non-volatile memory, read the corresponding instruction and then execute it, once this instruction has been executed, the processor 2 will be able to switch from an active mode to a passive mode in order to reduce the overall power consumption of the electronic watch circuit 1.
  • this embodiment where an interruption signal is used to allow the execution of instructions by the processor 2, is used for the execution of specific instructions.
