Problems solved by technology

In the above-mentioned system operation mode, not only the various microcontrollers cannot effectively control each other, but also it is difficult to accurately control the execution time for tasks that need to be executed immediately; in addition, it is very likely that due to improper work assignments to some microcontroller units , so that the performance of the overall multiple micro-control system cannot be effectively exerted
Therefore, the above-mentioned system operation mode is difficult to meet the increasingly complex performance requirements of electronic products

Embodiment Construction

[0057] The present invention is built on the structure of multiple micro-control systems. Each micro-controller core logic has the ability to independently process programs. Each micro-controller core logic can also assign the assigned program start address in the state of processing its own program. Into the program counter in the core logic of other microcontrollers, in this way, control the next task of the latter microcontroller core logic (controlled microcontroller core logic), so that the controlled microcontroller can be shortened The core logic transforms the latency of the executive program.

[0058] The first embodiment of the present invention is illustrated below. In the self-controlled multiple microcontroller system of the present invention, when one of the microcontroller core logics wants to control another unspecified microcontroller core logic, the system How it works and its method steps. Please refer to image 3 As shown, firstly, the self-controlled mul...

Abstract

The present invention discloses a self-controlled multiple micro-control system and its control method. In this multiple micro-control system, the core logic of any microcontroller can directly insert the start address of an inserted program into another controlled micro-controller. In the program counter in the core logic of the microcontroller, the program address when the core logic of the controlled microcontroller is interrupted is temporarily stored in the stack memory indicated by the stack pointer of the core logic of the microcontroller, so that the controlled After the core logic of the microcontroller finishes executing the inserted program, the original program can be re-executed from this breakpoint.

Description

technical field [0001] The invention relates to a multiple micro-control system and method, in particular to a multiple micro-control system and method with self-control capability. Background technique [0002] A microcontroller (Microcontroller Unit, MCU), or a microprocessor (Microprocessor Unit, MPU), also known as a single-chip microcomputer (Single Chip Microcomputer), is a computer that can independently perform calculations without other auxiliary circuits. Devices are mainly integrated circuit components responsible for the control functions in system products. A microcontroller is almost a miniature computer because it contains various functions provided by a complete computer. In recent years, microcontrollers have been widely used, including consumer electronics, industrial control, medical equipment, vehicle control, etc. According to different microcontroller specifications, they can be used in different fields, and the peripheral components controlled Also di...
