Multi-singlechip multitask cooperation circuit and method thereof

Abstract

The invention relates to a multi-singlechip multitask cooperation circuit which comprises a plurality of singlechips, a plurality of three-state gates, and three IO (input / output) port lines arranged on each singlechip and serving as control lines. The three control port lines arranged on each singlechip are a communication port line INT, a data port line DAT and a three-state gate enabling port line EN; the IO lines of the singlechips are connected with the corresponding three-state gates of the singlechips respectively; the three-state gates are enabled or disabled by the three-state gate enabling port lines EN to determine whether the singlechips are connected with other hardware; the communication port lines INT of the singlechips are connected mutually; and the data port lines DAT of the singlechips are connected mutually. With the adoption of the circuit, the singlechips can share the same hardware in a time-sharing manner, and multiple different programs can operate on the singlechips. The circuit has two operation modes: 1, the singlechips use the hardware in a time-sharing manner and software operates in a time-sharing manner so as to achieve the purposes of multiple functions, resource saving and instrumental function improvement; and 2, the singlechips use the hardware in a time-sharing manner and the software operates simultaneously to cooperate to accomplish a complicated algorithm.

Description

technical field [0001] The invention relates to a multi-single-chip multi-task cooperation circuit and a method thereof, belonging to the fields of electronic technology application and computer application research. Background technique [0002] Single-chip microcomputers are widely used in industrial fields due to their low price and powerful functions. In the application of single-chip microcomputer, we will find such a situation: several industrial control systems with single-chip microcomputer as the core, these systems have the same hardware except the software running in the single-chip microcomputer. However, if you want to complete several different control software on such a set of hardware to achieve different functions, making "one machine with multiple functions", it will be limited by the program storage space, data storage space, computing speed and complexity of the control software of the single-chip microcomputer. Restrictions such as degrees become diffic...

If we want to measure the above items on one machine, the traditional design method cannot do it

[0003] In addition, there will also be such a situation in the application system of single-chip microcomputer: although there is no requirement of "one machine with multiple functions", the algorithm is very complicated, and a single single-chip microcomputer is limited by the resources on the chip.
