Parallel computing asynchronous circuit

Abstract

The invention provides a parallel computing asynchronous circuit formed by connecting a large number of same asynchronous circuit modules in a uniform and adjacent mode. Each module can execute logical operation of life game cellular automata rules and is connected with the adjacent eight asynchronous circuit modules through a synchronizer. The state of each asynchronous circuit module is updated according to a state set of the other asynchronous circuit modules connected with the asynchronous circuit module. The synchronizer is switched on and outputs information only after receiving state information of the two corresponding asynchronous circuit modules connected with the synchronizer, and it is ensured that the states of all the asynchronous circuit modules are updated synchronously. The states of the asynchronous circuit modules are updated by means of the improved life game cellular automata rules. Each asynchronous circuit module representing life game cells achieves signal processing and state updating independently, it is ensued that the states of all the asynchronous circuit modules are updated synchronously by means of the synchronizer, and the parallel computing asynchronous circuit has the same rapid parallel computing power as a cellular automata.

Description

technical field [0001] The invention relates to an asynchronous circuit design method and the field of cellular automata, in particular to a parallel computing asynchronous circuit realized by using the game of life. Background technique [0002] The asynchronous circuit does not need a central clock signal in the circuit design, and the data exchange between the various modules of the system is completed through the handshake process between them. Asynchronous circuits have received more attention because of their advantages such as low power consumption, fast operation speed, good electromagnetic compatibility, strong reliability, and avoiding clock skew problems. However, asynchronous circuits lack corresponding EDA tools, and there are problems in design. Big flaw, slow progress in research and development. Although parallel processing technology has long been a hot topic in scientific research, the design of large-scale asynchronous circuits with ultra-parallel computi...

AI Technical Summary

Problems solved by technology

There is a central clock signal in the circuit to control the clock synchronization of the entire circuit, and thus has the inevitable disadvantages of a synchronous circuit, for example, high power consumption; the clock needs to be adjusted to be consistent with the slowest part of the circuit, so the speed is slow; it has always caused Offset issues; high noise, etc.
