Embedded designers can now combinedigital signal processing and MCU control code with the 32-bit PIC32 microcontroller family, using its no-cost, royalty-free High Performance DSP Library. This new library, which was added to the MPLAB® C Compiler for PIC32 MCUs at no additional cost, can execute a 256-point, 16-bit RADIX-2Fast Fourier Transform (FFT) in 283 microseconds, which is approximately 22% faster than Microchip’s previous PIC32 DSP Library. The free DSP Library in the Microchip C Compiler, combined with the industry’s highest-performing 32-bit MCU core, gives designers a single, low-cost and highly efficient platform for both control and signal-processing code…

Microchip Technology Enables Digital Signal Processing on the 32-bit PIC32 MCU Family Via Free High-Performance DSP Library

Optimized DSP Library Added to MPLAB® C Compiler for PIC32 MCUs; Enables 22% Increase in Fast Fourier Transform Speeds

Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced that embedded designers can now combine digital signal processing and MCU control code with the 32-bit PIC32 microcontroller family, using its no-cost, royalty-free High Performance DSP Library. This new library, which was added to the MPLAB® C Compiler for PIC32 MCUs at no additional cost, can execute a 256-point, 16-bit RADIX-2 Fast Fourier Transform (FFT) in 283 microseconds, which is approximately 22% faster than Microchip’s previous PIC32 DSP Library. A free evaluation version of this C Compiler, with included DSP Library, can be downloaded at http://www.microchip.com/c32.

Many embedded designers want to add base DSP capabilities—such as speech processing—to their 32-bit MCU applications, without incurring the cost of a DSP component. Microchip’s new DSP Library enables these capabilities by taking advantage of the highly optimized hardware features inside the PIC32 MCU, including its multiply-accumulate, math unit with parallel execution, and two full sets of CPU registers. Additionally, this DSP Library’s use of a RADIX-2 based FFT provides more options for sample size than the RADIX-4 designs used by competitors; the PIC32 DSP Library allows users to select from the common 64-, 128-, 256-, 512- and 1024-point FFTs, as well as other sizes. Microchip’s DSP Library also includes support for 32-bit FFTs, a feature not well supported by other MCU vendors.

“The free DSP Library in the Microchip C Compiler, combined with the industry’s highest-performing 32-bit MCU core, gives designers a single, low-cost and highly efficient platform for both control and signal-processing code,” said Derek Carlson, Microchip’s vice president of Development Tools.

The PIC32 DSP Library’s functions are C callable, so no Assembly coding is required. Users of Microchip’s dsPIC® digital signal controller families can easily migrate code to any PIC32 MCU, using a set of APIs that are compatible with the MPLAB C Compiler for dsPIC DSCs. Other key functions of the new PIC32 DSP Library include:

• 16- and 32-bit Vector Math
• Finite Impulse Response (FIR), Infinite Impulse Response (IIR) and east Mean Squares (LMS) Filters
• 16- and 32-bit Fast Fourier Transforms (FFTs)
