DSP Library for PIC32. The PIC32 DSP library consists of a set of functions applicable to many multimedia application areas. Most of the functions, like vector operations, filters, and transforms, are commonly used in many DSP and multimedia applications. Complete documentation for the PIC32 DSP Libraries can be found in the MPLAB C32 C Libraries Manual.

A PIC32 microcontroller equipped with one or more SPI interfaces supporting the "audio mode" gets exploited as digital signal processor for audio. By audio, I mean 44.1 kHz or 48 kHz 16-bit or 24-bit, always in stereo. The whole digital audio processing shall happen in the PIC32 SPI interrupt routine service :

Its really pretty simple. If you want to create a sine wave in a sample buffer of 32, you put the (amplitute*32)value in din [1].re. din [2].re for a double sine, and so on. So for a sample rate of 16000, 16000/32 = 500 * 1 = 500hz. Note that your output is in dout [x].re.

Digital Signal Processing PIC32MX250F128B . DSP -- FFT, IIR filters, Direct Digital Synthesis. Transfer function measurement It is useful to get the phase and magnitude of response of a circuit as a function of frequency. A DDS unit is used to synthesize a cosine wave, which is then played through a SPI attached DAC. The output of the DAC is attached to the circuit under test.

• Audio Protocol Interface mode Some PIC32 devices support audio codec serial protocols such as Inter-IC Sound (I2S), Left-Justified, Right-Justified, and PCM/DSP modes for 16, 24, and 32-bit audio data. Refer to the specific device data sheet for availability of these features. The SPIx serial interface consists of four pins:

Choosing a DSP for audio processing. ... The PIC32 does have single-cycle MACs, which makes it a possible candidate. Not sure if it's just 16x16 or 32x32, but it brings it close to the TI C2000 series, which is what I'm now leaning toward. Reply Start a New Thread.
