Research And Design Of Configurable Processor Based On TTA

Application-specific instruction set processors is a suitable choice as processors are being selected for the needs of digital signal processing applications. The Delft University of Technology from the Netherlands has proposed the TTA concept and develops semi-automated design tools, Move Framework, for designing application-specific instruction set processors.This design is optimized for DCT in Audio/Video domain and FFT in communication domain. The target is design a co-processor optimized for this two algorithms. And it could be shown that the processor has good performance and low power & area. Beside, Move Framework can design some special function unit can speed up target algorithms. This design has designed some special function unit for DCT and FFT. Via simulation and compare the performance between the CPU core with and without the special function unit, the performance highly increases after adding the special functional units.We have researched a design methodology that implements multiple algorithms in one processor. So it can be implement some complex algorithms like AVS on TTA through these design methodology.
