摘要：An inexpensive, high performance error detecting and correcting systemcapable of handling multiple errors with high throughput. Digital data is provided to areconfigurable decoder which is initially set for a low level of correction and a highthroughput. On detection of an error, a signal is generated which is used to dynamicallyreconfigure the decoder. The decoder is reconfigured at a higher correction level. Thedata is then reprocessed through the reconfigured decoder. In a specific implementation,the invention uses a Blahut decoder. N and K values to reconfigure the decoder areprovided by a microprocessor. The invention contemplates use of an encoder operatingat the highest level of correction required. Use of an initial low level of correctionprovides for a high throughput. Reconfigurability allows for high corrective power andassociated lower throughput only when necessary.
