  Abstract

This paper proposes an enhanced degree computationless modified Euclid's (E-DCME) algorithm and its architecture for Reed-Solomon decoders. The proposed E-DCME algorithm has shorter critical path delay that is Tmult + Tadd + Tmux compared with the existing modified Euclid's algorithm and the degree computationless modified Euclid’s (DCME) algorithm since it uses new initial conditions. The proposed E-DCME architecture employing a systolic array requires only 2t - 1 clock cycles to solve the key equation without initial latency. In addition, the E-DCME architecture consisting of 3t basic cells has regularity and scalability since it uses only one processing element. The E-DCME architecture using the 0.18㎛ Samsung standard cell library consists of 18,000 gates.
