Abstract:

An effective strategy for FIFO reset is introduced.In logical design,the FIFO is used for data storage.When the system is abnormal,FIFO may drop packet and cannot recover,in which case a soft FIFO reset is often used to to save the system at minimum cost.But the random FIFO reset may occur in the data packet processing,leading to incomplete packet writing into FIFO and thus system failure.Therefore a good FIFO reset strategy is necessary.
