Advance Information

16-BIT DIGITAL SIGNAL PROCESSOR

The general-purpose, programmable DSP56167 is an enhanced version of the DSP56166 with

added features. Designed primarily for speech coding and digital communications, the

DSP56167 has a built-in

memories and digital peripherals that provide a cost effective, high performance solution to

many DSP applications. On-Chip Emulation (OnCE ) circuitry provides convenient and

inexpensive debug facilities normally available only through expensive external hardware. This

RAM-based DSP contains a 2 K 16 Program RAM and a 4 K 16 data RAM. The Central

Processing Unit (CPU) consists of three execution units operating in parallel allowing up to six

operations to occur in an instruction cycle. This parallelism greatly increases the effective

processing speed of the DSP56167. The MPU-style programming model and instruction set

allow straightforward generation of efficient, compact code. The DSP56167 is a member of

Motorola’s DSP56100 family of 16-bit Digital Signal Processors (DSPs).
