Cummings 1. 异步FIFO指针. 对于同步FIFO来说(即FIFO Read/Write处于一个时钟域),使用一个CNT作为指针即可。当指针指向预定的满值时,FIFO标记为满,指针指向0时,FIFO为空。 而对于异步FIFO而言这种方法是不可行的,因为异步FIFO的Read ... WebClifford E. Cummings Sunburst Design, Inc. ABSTRACT FIFOs are often used to safely pass data from one clock domain to another asynchronous clock domain. Using a FIFO to pass data from one clock domain to another clock domain requires multi-asynchronous clock design techniques. There are many ways to design a FIFO wrong. tail underwear for men
