The device contains two 24-bit 40 MIPS DSP cores delivering a total of 80 MIPS of DSP processing power. There is also an embedded 8bit 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.
