DESCRIPTION The device is a high-performance Digital Signal Processing IC particularly suited to Audio applications. The device contains two 24-bit 42 MIPS DSP cores delivering a total of 84 MIPS of DSP processing power. There is also an embedded 8-bit Microcontroller to handle all control functions. All data and program memories for both DSP cores are on-chip. A variety of highly programmable and flexible peripheral blocks for both the Microcontroller and the DSPs have been integrated to form a powerful audio processing system on a single chip.
