摘要
Abstract
In view of the possible failures of the traditional asynchronous FIFO in OTN circuits,this paper proposes a kind of a-synchronous FIFO suitable for OTN circuits,in which reading/writing addresses will be reset when empty/full emerges in the asynchronous FIFO,without affecting the simultaneous read/write functions of the circuits.It is easier to judge whether the a-synchronous FIFO is in empty or full state by comparing the highest two read/write addresses to determine if the indicator sig-nal close to empty or to full.The test results show that the designed FIFO empty/full resetting function is normal and the read/write rate can reach up to 133 MHz.关键词
