CHIEN-SEARCH SYSTEM EMPLOYING A CLOCK-GATING SCHEME TO SAVE POWER FOR ERROR CORRECTION DECODER AND OTHER APPLICATIONS |
摘要 |
Chien search apparatus operative to evaluate an error locator polynomial having a known rank and including a sequence of terms for each element in a finite field whose elements correspond respectively to bits in each of a stream of data blocks to be decoded, the apparatus comprising a sequence of functional units each operative to compute a corresponding term in the sequence of terms included in the error locator polynomial, each term having a degree; and a power saving unit operative to de-activate at least one individual functional unit from among the sequence of functional units, the individual functional unit being operative, when active, to compute a term whose degree exceeds the rank.
