摘要:
Various systems and methods for generating and/or ordering error indications are disclosed herein. In some cases, the error indication is used as an erasure pointer in a memory access system. As one particular example, a system for ordering erasure pointers is disclosed that includes a group of N sort cells, where N is a whole number. Each of the sort cells is operable to maintain a respective error indication that includes an error value and an associated error pointer. Further, the group of N sort cells is operable to receive an incoming error indication including error value and associated error pointer, and to update the error indication of one or more of the group of N sort cells based in part on the incoming error value. The system also includes a selector circuit that is operable to allow selectable access to each of the respective error pointers maintained in the group of N sort cells.
