Abstract
A shared decoder pool is susceptible to head-of-line blocking when the decoding of a given data block delays the decoding of other data blocks pipelined in the decoder. While the problem can be avoided by not using a pipeline operation, the benefits of pipelining would be lost. In one embodiment provided herein, the syndrome of an error pattern is calculated in parallel with data being written in an input buffer for the decoder. Parallelizing the syndrome calculation and the filling of the decoder's input buffer can avoid the head-of-line blocking problem noted above while still achieving the benefits of pipelining. In another embodiment, a similar technique is used in a bit error rate estimation scan (BES) operation. Other embodiments are provided.
