FPGA-Extended General Purpose Computer Architecture

This paper introduces a computer architecture, where part of the instruction set architecture (ISA) is implemented on small highly-integrated field-programmable gate arrays (FPGAs). Small FPGAs inside general-purpose processor (CPU) can be used effectively to implement custom or standardised instructions. Our proposed directly address related challenges for high-end CPUs, such would have highest impact, as main memory bandwidth. also enables software-transparent context-switching. The simulation-based evaluation dynamically reconfigurable core shows promising results approaching performance an equivalent with all enabled Finally, feasibility adopting in today’s CPUs studied through prototyping fast-reconfigurable and profiling miss behaviour opcodes.
