A portable and Linux capable RISC-V computer system in Verilog HDL
share
RISC-V is an open and royalty free instruction set architecture which has been developed at the University of California, Berkeley. The processors using RISC-V can be designed and released freely. Because of this, various processor cores and system on chips (SoCs) have been released so far. However, there are a few public RISC-V computer systems that are portable and can boot Linux operating systems. In this paper, we describe a portable and Linux capable RISC-V computer system targeting FPGAs in Verilog HDL. This system can be implemented on an FPGA with fewer hardware resources, and can be implemented on low cost FPGAs or customized by introducing an accelerator. This paper also describes the knowledge obtained through the development of this RISC-V computer system.
