摘要
Provided are an operation circuit for a modified Euclidean algorithm in a high-speed Reed-Solomon (RS) decoder and a method of implementing the modified Euclidean algorithm. Since a finite state machine (FSM) for generating a stop signal and an FSM for generating a control signal that controls a swap operation, a shift operation, and a polynomial operation for each basic cell of the modified Euclidean algorithm are used, an area-efficient RS decoder can be realized without using a conventional degree computation unit for comparing and calculating degrees.
