一种基于ASIC的高速异步FIFO设计
A design of high-speed asynchronous FIFO based on ASIC
摘要
Abstract
This paper analysis the structure and key technology of asynchronous FIFO. Compared with the method of using Gray code as the pointer of asynchronous FIFO, the paper presents a method that shift code is instead of gray code. This new design has the following advantages. Firstly, the probability of occurrence in metastability is reduced. Secondly, the circuit structure, area and the pow- er consumption are more simple, small and lower. Also, the key path of the circuit is shortened. The result is the circuit＇s working frequency is improved significantly. The results of simulation and synthesis shows that this FIFO is stable and reliable.关键词
