Bluetooth V1.2 Class 2 Module
Data Book
The key features of the DSP include:
ƒ 32MIPS performance, 24-bit fixed point DSP Core
ƒ Single cycle MAC of 24 x 24-bit multiply and 56-bit accumulate
ƒ 32-bit instruction word
ƒ Separate program memory and dual data memory, allowing an ALU
operation and up to two memory accesses in a single cycle
ƒ Zero overhead looping and branching
ƒ Zero overhead circular buffer indexing
ƒ Single cycle barrel shifter with up to 56-bit input and 24-bit output
ƒ Multiple cycle divide (performed in the background)
ƒ Bit reversed addressing
ƒ Orthogonal instruction set
ƒ Low overhead interrupt
3.5 Audio Interface
The audio interface circuit consists of a stereo audio CODEC, dual audio inputs
and outputs, and a PCM, I²S or SPDIF configurable interface.
The interface for the digital audio bus shares the same pins as the PCM CODEC
