First-In First-Out Buffer with Lookahead Performance Booster

Abstract:

A FIFO may use lookahead circuitry to boost performance and reduce data transfer latency by reducing the FIFO operation cycles when operating in the store and forward mode. The lookahead circuitry may increase data transfer rate of the FIFO between two integrated circuit devices that use different clock frequencies. The use of the lookahead circuitry with the FIFO may also reduce power consumption of the FIFO, allow storage media of the FIFO to be smaller, and free up valuable die space for other circuitry.
