DSP56367
24-Bit Audio Digital Signal Processor
1
This document briefly describes the DSP56367 24-bit
digital signal processor (DSP). The DSP56367 is a
member of the DSP56300 family of programmable
CMOS DSPs. The DSP56367 is targeted to applications
that require digital audio compression/decompression,
sound field processing, acoustic equalization and other
digital audio algorithms. The DSP56367 offers 150
million instructions per second (MIPS) using an internal
150 MHz clock at 1.8 V and 100 million instructions per
second (MIPS) using an internal 100 MHz clock at 1.5 V.
