16-bit Digital Signal Processor

DSP56156
This product has been discontinued.

The DSP56156 is a general-purpose MPU-style Digital Signal Processor (DSP). On a single semi-conductor chip, the DSP56156 comprises a very efficient 16-bit digital signal processing core, pro-gram and data memories, a number of peripherals, and system support circuitry. features of the DSP56156 include a built-in sigma-delta codec and phase-locked loop (PLL). This combination of features makes the DSP56156 a cost-effective, high-performance solution for many DSP applications, especially speech coding, digital communications, and cellular base stations. The central processing unit of the DSP56156 is the DSP56100 core processor. Like all DSP56100- based DSPs, the DSP56156 consists of three execution units operating in parallel, allowing up to six operations to be performed during each instruction cycle. This parallelism greatly increases the effective processing speed of the DSP56156. The MPU-style programming model and instruction set allow straightforward generation of efficient, compact code. The basic architectures and development tools of Motorola's 16-bit, 24-bit, and 32-bit DSPs are so similar that understanding how to design and program one greatly reduces the time needed to learn the others. On-Chip Emulation (OnCE TM port) circuitry provides convenient and inexpensive debug facilities normally available only through expensive external hardware. Development costs are re-duced and in-field testing is greatly simplified using the OnCE TM port.
