  • Abstract
    A novel mixed signal 32-bit rotator/shifter circuit design enabling ultra-short latency Intel® Netburst™ rotate and shift instructions is described. Compared to previous generation Intel® Pentium® 4 processor designs, this implementation cuts Rotate/Shift latency and throughput by 75% while adding significant frequency headroom. The circuit manufactured on Intel´s 90nm process confirms a significant boost in integer performance.
