Discrete Convolution and Correlation

In this experiment , Convolution and Correlation algorithms were emulated on the DSP Processor TMS320F28335.
For a Linear Time Invariant system,Convolution is basically smearing the input signal with another signal to get the output. Convolution algorithms are used in image processing for smoothing of an image. Correlation is used to measure the extent of similarity between  two signals. The value of correlation coefficient indicates the degree of similarity.

    The 'MPY' and 'MAC' assembly instructions in DSPs are commonly used for performing convolution as they facilitate parallel operation.

      Yes, many of these advanced assembly instructions are executed in a single instruction cycle since the processor has a dedicated hardware.
