This thesis is proposed with latency optimization through threshold control for FIFO is designed by using FIRST WORD FALL THROUGH(FWFT).Almost_full parameter is used to read data even the read enable is not high.The data is read immediately when the data is written after the write pointer exceeds threshold value.The proposed FIFO architecture supports configurable data width and memory depth, enabling scalability and flexibility for various FPGA-based applications using FWFT mode. The FIFO design incorporates dedicated read and writes pointer management, full and empty status flag generation.Synthesis and implementation results demonstrate successful FIFO operation with efficient resource utilization and reliable data transfer.
