ENCODING DEVICE AND ENCODING METHOD FOR TWO-DIMENSIONAL PRODUCT CODES BASED ON EXTENDED HAMMING CODES

摘要

An encoding device and an encoding method for two-dimensional product codes based on extended hamming codes. The encoding device comprises: an information input cache module, an encoding information storage circuit module, a subcode encoding logical circuit module and an encoding control circuit module. The subcode encoding logical circuit module comprises a reconfigurable row code encoding arithmetic circuit and a reconfigurable column code encoding arithmetic circuit. In the device, a register block is used for information storage, an encoding arithmetic circuit module is then used for two-dimensional product encoding, and an encoding control circuit module is used for controlling each time sequence to implement synchronization of row and column encoding and generation of twin check bits during output of encoding information, so that an encoding delay is greatly reduced, and the throughput of an encoding circuit is increased.
