1. Processors in digital processing

Generally speaking, the architecture of a digital signal processing system can be represented very schematically by the figure 1 .

In all the fields mentioned as examples, there are processes that use functions:

  • filtering (convolution operations) ;

  • matrix calculation ;

  • complex transformations (FFT, DCT...) ;

  • signal generation ;

  • calculation of statistical characteristics such as averages, intercorrelations and autocorrelations, etc.

Depending on the frequency characteristics of the phenomena under study and the computational load to be implemented, this...
