“…The Reed-Solomon code is defined in the Galois field which contains a finite set of numbers where any arithmetic operations on elements of that set will result in an element belonging to the same set [6]. Every element, except zero can be expressed as a power of a primitive element, α of the field.…”

This paper presents a design of syndrome computation block for Reed-Solomon decoder for RS (255, 239) code. For calculating the syndromes, three-parallel processing has been used. Parallelizing allow inputs to be received at very high rates and outputs to be delivered at correspondingly high rates with minimum delay. RS (255, 239) code consists of 255 symbols which are multiple of 3. So three symbols are inputted parallely in syndrome computation block. This process can be adapted in the FEC devices.
