摘要:

本文采用基于宏单元的异步集成电路设计流程,实现了可用于ASIP的4段流水32位异步加法单元,并实现了其同步版本作为对比。通过仿真分析,异步加法单元性能与同步加法单元相近,在功耗方面则具有相当大的优势。

Abstract:

An asynchronous integrated circuit design flow based on macro cells is described. Using this design flow, a 32-bit 4-sector pipelined asynchronous adder in ASIPs is designed. Compared with the synchronous version, the asynchronous adder has the similar performance and the advantage of power consumption.

Key words: asynchronous adder, power consumption, performance, design flow
