A timeshared, runtime reconfigurable hardware co-processing architecture

[摘要] The constant desire for increased performance in microprocessor systems has led to the need for specialized hardware cores to accelerate specific computational tasks. In this thesis, we explore the potential of using FPGA partial reconfiguration to create a platform for customized hardware cores that may be loaded on demand, at runtime, and replaced when not in use. We implement two new software tools, bitparse and bitrender, to demonstrate the bitstream relocation technique. Further, we present a functional microprocessor system coupled with a runtime reprogramable peripheral synthesized on a Xilinx Virtex-5 FPGA and discuss its performance implications.
