Digital Audio Processor (DAP) Arithmetic Unit
The DAP arithmetic unit is a fixed-point computational engine consisting of an arithmetic unit and data and
coefficient memory blocks. The primary features of the DAP are:
Two-pipe parallel processing architecture
–
48-bit data path with 76-bit accumulator
–
Hardware single cycle multiplier (28×48)
–
Three 48-bit general-purpose data registers and one 28-bit coefficient register
–
Four simultaneous operations per machine cycle
–
Shift right, shift left, and bimodal clip
–
Log2/Alog2
–
Magnitude Truncation
Hardware acceleration units
–
Soft volume controller
–
Delay memory
–
Dither generator
–
Log2/2× estimator
1024 + 768 dual-port ports words of data (24 and 48 bits, respectively)
1228 words of coefficient memory (28 bits)
3K word of program RAM (55 bits)
5.88K words of 24-bits delay memory (1.22 ms)
Coefficient RAM, data RAM, LFSR seed, program counter, and memory pointers are all mapped into
the same memory space for convenient addressing by the microcontroller.
Memory interface block contains four pointers, two for data memory and two for coefficient memory.
