We present RAMP Gold, an economical FPGA-based archi-
tecture simulator that allows rapid early design-space explo-
ration of manycore systems. The RAMP Gold prototype is
a high-throughput, cycle-accurate full-system simulator that
runs on a single Xilinx Virtex-5 FPGA board, and which
simulates a 64-core shared-memory target machine capable
of booting real operating systems. To improve FPGA imple-
mentation efficiency, functionality and timing are modeled
separately and host multithreading is used in both mod-
els. We evaluate the prototype's performance using a mod-
ern parallel benchmark suite running on our manycore re-
search operating system, achieving two orders of magnitude
