Abstract

In this investigation, we present a semisystolic type-t(t is even) Gaussian normal basis(GNB) multiplier. Compared with the only existing bit parallel semisystolic even type GNB multiplier, our multiplier saves 10% space complexity and has 50% increase on throughput under the same time complexity. Based on the proposed multiplier, two multipliers with concurrent error detection(CED) capability are developed using two different schemes. The second multiplier with CED capability outperforms previous related works and can be further simply modified to correct certain multiple errors for GNB with type t≥6. Moreover, both the multipliers with CED capability have a high fault coverage. Our results show that any single-cell fault can be detected.
