BCH Error Correction Encoder and Decoder

Block Diagram

Solution Type: IP Core

End Market: Automotive, Computer & Storage, Industrial, Medical, Military, Wireline

Evaluation Method: OpenCore

Technology: DSP: Error Detection and Correction

Arria Series: Arria 10, Arria V, Arria 10 SoC, Arria V SoC

Cyclone Series: Cyclone IV, Cyclone V, Cyclone V SoC

Stratix Series: Stratix IV, Stratix V

Overview

The Octera BCH core consists of an encoder and decoder. The decoder implements the standard steps of calculating the syndromes followed by calculating the error location polynomial using Galois Field mathematics in hardware. The final correction uses a method that is more readily pipelined than the common Chien search.
