The DSP core contains three independent computation units:

• ALU

Performs a standard set of arithmetic and logic operations in both

fixed-point and floating-point formats.

• Multiplier with a fixed-point accumulator

Performs floating-point and fixed-point multiplication, and

fixed-point multiply/add and multiply/subtract operations.

• Shifter

Performs logical and arithmetic shifts, bit manipulation, field

deposit and extraction, and exponent derivation operations on

32-bit operands.

For meeting a wide variety of processing needs, the computation units

process data in three formats

• 32-bit, fixed-point

• 32-bit, floating-point

• 40-bit, floating-point
