Abstract
Chien search is a computation-intensive VLSI design in BCH (Bose-Chaudhuri-Hocquenghem) decoders for a variety of applications such as digital video and data storage. Existing low power approaches to this subject are effective only for single-bit error case, and their power efficiency decreases dramatically for multiple-bit-correcting code. This paper presents a novel approach of using register-transfer-level (RTL) power management in the search process, leading to significant power savings for BCH codes with higher correction capability. A (255, 187, 9) BCH code is implemented in 0.18μm CMOS technology as an example.
