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.

Verilog HDL 中的便携式且支持 Linux 的 RISC-V 计算机系统

RISC-V 是一种开放且免版税的指令集架构，由加州大学伯克利分校开发。使用RISC-V的处理器可以自由设计和发布。因此，迄今为止已经发布了各种处理器内核和片上系统 (SoC)。但是，有一些公共 RISC-V 计算机系统是便携式的，可以启动 Linux 操作系统。在本文中，我们描述了一个以 Verilog HDL 为目标的便携式且支持 Linux 的 RISC-V 计算机系统。该系统可以在硬件资源较少的FPGA上实现，也可以在低成本的FPGA上实现，也可以通过引入加速器来定制。本文还描述了通过开发这个 RISC-V 计算机系统获得的知识。
