A hybrid radix-4/-8 truncated multiplier is proposed for mobile graphics processing unit (GPU) applications by combining the strong points of high-speed radix-4 and low-power radix-8 encoding schemes. A hybrid Booth encoder (HBE) for radix-4/-8 encoding is proposed by sharing the common logics between the two encodings. In addition, a hybrid radix-4/-8 truncation (HRT) scheme is proposed for more power reduction at a reasonable peak signal-to-noise ratio loss for mobile multimedia applications. Experimental results demonstrate 29.7 and 31.1% power savings from the HBE and the HRT schemes, respectively, resulting in a total of 60.7% power reduction from the previous work.
