Abstract:
The paper deals with various approaches used for parallel computing in signal processing domain. More precisely, the methods exploiting the multicores Central Processing Units such as Message Passing Interface and OpenMP are taking into account. The properties of the programming methods are experimentally proved in application of two-dimensional Fast Fourier Transform and Discrete Cosine Transform and are compared with possibilities of MATLAB built-in functions and Digital Signal Processors with Very Long Instruction Word architecture. The optimal combination of computing methods in signal processing domain is proposed. Results in the paper prove the possibility of creation of a~heterogeneous computing system compounded of CPU and DSP architectures.
