DSP56002

The DSP56002 is a MPU-style general purpose Digital Signal Processor (DSP) composed of an

efficient 24-bit DSP core, program and data memories, various peripherals, and support

circuitry. The DSP56000 core is fed by on-chip Program RAM, and two independent data RAMs.

The DSP56002 contains a Serial Communication Interface (SCI), Synchronous Serial Interface (SSI),

parallel Host Interface (HI), Timer/Event Counter, Phase Lock Loop (PLL), and an On-Chip

Emulation (OnCE™) port. This combination of features, illustrated in Figure 1, makes the

DSP56002 a cost-effective, high-performance solution for high-precision general purpose digital

signal processing.
