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...
