[quote]Is it possible to do convolution in MSP430F5529 ???[/quote] Within the Flash (code) and RAM (data) size constraints, you can implement almost any algorithm. But more important are your requirements. How fast needs it to be done ? What a resolution (block size/input size) is required ? As an example, FFT implementations are occasionally discussed here. FFTW, a renowned library for Unix/Linux/Windows, supports arbitrary input and FFT block sizes. Doing an audio signal analysis on 44.1kHz input data with a 1Hz spectral resolution is not uncommon. That would be hardly possible with a 16-bit MCU, having a few kilobytes of RAM.
