Abstract:
1. An apparatus that has Chien search capabilities, the apparatus comprising: a first hardware circuit to evaluate an error locator polynomial for a first element of a finite field over which the error locator polynomial is defined, and to provide a first set of intermediate results and a first Chien search result; and a second hardware circuit, wherein the first hardware circuit is to provide the first set of intermediate results to the second hardware circuit, and wherein the second hardware circuit is to evaluate the error locator polynomial for a second element of the finite field to provide a second Chien search result in response to the first set of intermediate results; wherein the first hardware circuit comprises a mask and add unit to sum unmasked bits representative of preliminary results obtained during an evaluation of the error locator polynomial to provide the first set of intermediate results.
