  • Abstract
    A 1-pipe stage, low-latency, 13 FO4, 64b fixed-point execution unit, implemented in a 65nm SOI CMOS process, allows back-to-back execution of data dependent adds, subtracts, compares, shifts, rotates, and logical operations. A 7-pipe stage, 91 FO4, double-precision floating-point unit allows forwarding of dependent results after 6 cycles in most cases
