To increase system composability and facilitate timing closure, fully synchronous clocking is replaced by more relaxed schemes, such as mesochronous clocking. Under this regime, the modules at two ends of a interface receive same clock signal, thus operating under frequency, but edges arriving signals may exhibit an unknown phase relationship. In cases, synchronization needed when sending data across modules. brief, we present novel dual-clock first-input-first-output (FIFO) buffer that can...
