Parallel Reed-Solomon for Fault-tolerant Systems

ECC Tek's patented Parallel RS (PRS) encoder and decoder designs are used to design fault-tolerant parallel storage and communications systems.

ECC Tek’s PRS designs are the de facto standard for space to create fault-tolerant synchronous DRAM memories.

ECC Tek's existing PRS encoder and decoder designs are used to correct two or three 4-bit symbols or "nibbles" in 32-bit data words.

A block diagram of a PRS encoder is shown below. All of the message symbols are received and operated on simultaneously and all of the R symbols of redundancy are generated in one step.
