Abstract: In this article, 8-bit bit-slice butterfly processing units (BPUs) are proposed for 64-point rapid single-flux-quantum (RSFQ) fast Fourier transform processors. The BPUs are based on radix-2 ...

Abstract: Modified Discrete Cosine Transform (MDCT) is widely used in current audio codec for its excellent performance in frequency selectivity during critical sampling. To avoid lossy codec which ...
