MB86330

s DESCRIPTION

The MB86330 is a 16-bit fixed-point DSP (Digital Signal Processor) that is based on Fujitsu-specific Dual-MAC

architecture, and can implement product addition operations and double transfer at a high rate and under low

power consumption.

The DSP supports a set of instructions optimum for digital signal processing in communications applications such

as handy phones.

The MB86330 consists of a core section and a peripheral section. For detailed specifications of the core section,

see MB86330DSP Core Section Specifications.

s FEATURES

• Fixed-point operations

Multiplication: 16 bits × 16 bits → 31 bits

Addition: 40 bits + 40 bits → 40 bits

Product addition: 40 bits ±16 bits × 16 bits → 40 bits
