A Superscalar Out-of-Order x86 Soft Processor for FPGA | TSpace Repository
Title: A Superscalar Out-of-Order x86 Soft Processor for FPGA Abstract (summary): Although FPGAs continue to grow in capacity, FPGA-based soft processors have grown very little because of the difficulty of achieving higher performance in exchange for area. Superscalar out-of-order processor microarchitectures have been used successfully for hard processors for many years, and promise large perform
