Efficiency of the signal processing algorithms using signal-flow based mapping tool

This paper is dealing with the implementation of the signal processing algorithms, specifically the Fast Fourier Transform and the matrix multiplication, using the new tool for mapping instructions on functional units of the processor. The tool is using the signal-flow based description of the algorithm instead of the sequential notation of the program execution.

The selected target processor is a multi-core digital signalprocessor based on the very long instruction word architecture. The final assembly code is analyzed in terms of utilization of the functional units and general purpose registers.
