In some of my past articles on the PowerQuad, we examined some common signal processing operations (IIR BiQuad and the Fast Fourier Transform) and then showed how to use the PowerQuad DSP engine to accelerate the computations. The matrix engine in the PowerQuad can be used to perform common matrix and vector operations to free the M33 CPU(s) to perform other tasks in parallel. In general, the matrix engine is limited to a maximum size of 16x16 size (or 256 operations).
