Abstract :
This paper presents a pipelined dataflow architecture for asynchronous systems, and a small micro-coded processor is constructed to realize this architecture. This pipelined dataflow approach allows different arithmetic units to operate at the same time and thus a shorter computation time and higher throughput rate can be achieved. This proposed architecture is suitable for DSP applications and an implementation of Discrete Cosine Transform (DCT) is shown at the end of this paper
