Abstract :
This paper describes tests performed by parallel signal processing algorithms on Texas Instruments 8-core digital signal processor and Intel Core i7. Tests reveal how the change of number of threads and size of input data influences the performance compared with sequential code. The result of the test is that the relative speedup is highly dependent on type of the algorithm and the amount of processed data.
