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.
