Abstract;This paper studies DSP system architecture optimization method using digit serial operation under the throughput constraint. The proposed method can make the DSP system design considering the trade-offs between the hardware cost and the throughput which are introduced by efficient digit size conversions. Experimental results show the trade-offs between the hardware cost and the throughput and the optimum architecture of DSP system can be decided using proposal digit size conversion algorithm under the throughput constraint.
