Problems solved by technology

However, not all CPUs have the function of inserting and waiting. At this time, the synchronization and anti-collision of two software or processors becomes difficult. Using some other methods can also achieve the purpose of anti-collision, but all need to increase software and hardware. overhead, which complicates the design

Embodiment Construction

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0026] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0027] Such as figure 1 As shown, the synchronous control circuit provided by the present invention includes CPU1, dual-port memory and CPU2, and both CPUs are connected to the dual-port memory, that is, the two CPUs can perform read and write operations on the dual-port memory.

[0028] The same clock signal output by a clock signal source is output to two CPUs at the same time. This clock signal source can be generated inside the system or by an external device.

[0029] A communication control so...

Abstract

The invention discloses a system communication and control processing synchronization method, and relates to the field of computer processing communication control. The invention aims at providing a simple and feasible system communication and control processing synchronization method increasing no hardware overhead. The technical essential of the system communication and control processing synchronization method provided by the invention comprises the following steps: connecting two processors to a double-port memory, and connecting clock signals output by a clock generator to the two processors at the same time, wherein the first processor is used for communication, and the second processor is used for control processing; allocating high levels of the clock signals to the first processor; and allocating low levels of the clock signals to the second processor.

Description

technical field [0001] The invention relates to the field of computer processing communication control. Background technique [0002] Generally speaking, inside the computer, the benefits of using a processor (CPU) for communication and control processing are unquestionable, such as fewer software, tighter coupling between software modules, easier control of the process, and basically no Synchronization problems arise. [0003] However, in some devices, processors with powerful processing functions and resources cannot be used due to cost, device grade, procurement and other reasons. Sometimes the software functions have to be split. The split software modules have their own performance and Processing devices with slightly weaker resources. In actual design, it is common practice to split a communication control software into a communication function part and a processing control part. Communication and synchronization issues, if not handled properly, may cause errors in ...
