RISC-V Processor With FPGA Hardware Acceleration

The patent applies dynamics by making the computation device reconfigurable through FPGA technology. The special-purpose computation logic can be dynamically changed by loading different binary files into the FPGA unit, allowing the same hardware to adapt to different computational tasks without physical remanufacturing. This resolves the contradiction by providing ASIC-like performance for specific tasks while maintaining the flexibility to change functions through software updates rather than hardware redesign.

The patent merges the general-purpose processor and FPGA into a single integrated chip. The FPGA unit is directly coupled to the RISC-V processor core on the same substrate, eliminating the need for external bus interfaces and separate chip communication protocols. This integration reduces system complexity while maintaining the flexibility benefits of FPGA technology, as the special-purpose computation can be seamlessly coordinated with the processor through internal connections rather than external bus structures.

The patent implements dynamics by making the instruction set extension configurable through software rather than fixed in hardware. The FPGA unit can be reconfigured by loading different binary files that define different extended instruction sets and corresponding computation logic. This allows the system to maintain high-performance computation for current tasks while adapting to future requirements by simply updating the FPGA configuration, eliminating the need for hardware redesign.

The patent eliminates the need for high-speed serial interface protocols by integrating the FPGA unit directly with the RISC-V processor on the same chip. Data transmission between the processor and FPGA occurs through internal chip connections rather than external bus structures, removing the complexity of protocol implementation while maintaining high-speed communication through direct internal pathways.
