DSP56824 16-Bit Digital Signal Processor
The DSP56824 is a member of the DSP56800 core-based family of Digital Signal Processors (DSPs). This
general purpose DSP combines processing power with configuration flexibility, making it an excellent
cost-effective solution for signal processing and control functions. Because of its low cost, configuration
flexibility, and compact program code, the DSP56824 is well-suited for cost-sensitive applications, such as
digital wireless messaging, digital answering machines/feature phones, modems, and digital cameras. The
DSP56800 core consists of three execution units operating in parallel, allowing as many as six operations
per instruction cycle. The MPU-style programming model and optimized instruction set allow
straightforward generation of efficient, compact DSP and control code. The instruction set is also highly
efficient for C Compilers. The DSP56824 supports program execution from either internal or external
memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The rich
set of programmable peripherals and ports provides support for interfacing multiple external devices, such
as codecs, microprocessors, or other DSPs. The DSP56824 also provides two external dedicated interrupt
lines and sixteen to thirty-two General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration (see Figure 1).
