Application Report Abstract

Optimizing DSP-Based Digital Filters With Application-Specific FIFOs

The TI SN74ACT36xx 36-bit clocked FIFO family interfaces to a 32-bit floating-point DSP, allowing high-integrity data transfer and improving system throughput. This document describes the patented synchronous retransmit FIFO feature used with a DSP for FIR digital filtering. Two examples of DSP application specific FIFOs are given. The first uses the unidirectional SN74ACT3641 (1024 ? 36) FIFO and the second uses the SN74ACT3638 (512 ? 32 ? 2) bi-directional clocked FIFO.
