DSP Library for dsPIC33A DSCs

The DSP Library for dsPIC33A DSCs is a comprehensive suite of Digital Signal Processing (DSP) functions designed to facilitate the development of high-performance signal processing applications. By utilizing pre-built functions which are optimized to take advantage of the dsPIC33A DSC architecture, you can substantially decrease your development time while improving the efficiency and precision of your signal processing tasks.

The DSP ISA support in the dsPIC33A family includes specialized instructions for DSP tasks. These instructions are optimized for operations such as single cycle multiply-accumulate (MAC), and the library leverages these instructions for efficient execution of algorithms.

The DSP library optimized for the 32-bit dsPIC33A CPU is now compatible with the Common Microcontroller Software Interface Standard (CMSIS) DSP open-source software framework. The library (dspic33-cmsis-dsp) supports fixed-point functions (q31) and floating-point (f32) using the hardware Floating Point Unit (FPU).

List of Supported Mathematical and Signal Processing Functions:

• Basic Mathematics (including Vector functions)
• Complex Mathematics
• Window Functions
• Matrix Functions
• Filtering Functions
• Transform Functions
• Controller Functions
• Conversion Functions
• Statistics Functions
• Support Functions

Classic DSP Library Usage in C Code Applications

Note: For new designs, consider using CMSIS DSP library for dsPIC33A DSCs

While we provide CMSIS compatible DSP library for our dsPIC33A DSCs, our classic DSP library for the dsPIC33A devices will be maintained and it comes pre-installed with the MPLAB® XC-DSC compiler, located at its install directory.
