DSPcore
A DSP core, or digital signal processing core, is a specialized processor designed for real-time numerical computations typical of signal processing tasks. It emphasizes high sustained throughput and predictable latency, often at low power, to handle streaming data such as audio, video, and communications signals.
A typical DSP core includes a multiply-accumulate MAC unit, a pipelined datapath, and support for fixed-point
Memory architectures for DSP cores often use a Harvard or modified Harvard arrangement, with fast on-chip RAM
Software ecosystems typically include cross-compilers, assemblers, libraries for DSP tasks (FIR/IIR filtering, FFTs, codecs), and real-time
Applications of DSP cores span audio processing, telecommunications, radar and sonar, image and video processing, and
Representative examples of DSP cores include TI’s TMS320/C6000 family, Analog Devices SHARC cores, and ARM Cortex-M4/M7
