DSP USING MULTI-SEGMENTED BUSES EQUIPPED WITH PLURAL PROCESSORS PERFORMING FFT, AND METHOD THEREOF

摘要

PURPOSE: A DSP(Digital Signal Processor) using multi-segmented buses and a method thereof are provided to perform the IPC(Inter-Processor Communication) at the same time by using the buses of a small size. CONSTITUTION: The processors perform the FFT(Fast Fourier Transform). The DSP performs the IPC at the same time by using processors as an intersecting point and respectively matching at least more than two buses with the processors. The buses are equipped with the first buses respectively connecting the processors of a predetermined unit among the processors, and the second buses respectively connecting the processors connected through the respective first buses to the first buses in a lattice shape.
