RISC-V调试标准主要包含RISC-V调试规范(Debug Specification)。它定义了调试接口和协议,为RISC-V处理器的调试提供统一的框架 。 从调试接口来看,RISC-V调试规范定义了一个标准化的调试访问端口(Debug Access Port,DAP)。这个端口通常基于JTAG(Joint Test Action Group)或SWD(Serial W

Lauterbach RISC-V Debugger | 17 Explicit JTAG-DTM + DM Configuration via RVDMIAP + COREDEBUG The RISC-V debug specification defines the RISC-V JTAG Debug Transport Module (JTAG-DTM), which is a standardized RISC-V IP block that can access the debug registers of the RISC-V Debug Module ...

具体实现(implementation)中还可以包含一个debug mode,以支持片外调试和/或制造测试。debug mode(D-mode)可被看作为一个额外的特权模式,它的权限甚至比M-mode还多。分离出的debug specification中描述了debug mode下RISC-V hart的操作。debug mode保留了一些CSR地址,这些地址只能在D mode下访问,此外也可以在平台上...
RISC-V ABIs Specification, Version 1.0相关章节:Volume I Chapter 2 – Chapter 4 按照通用寄存器的位宽和数量分类,RISC-V指令集包含四种基础整数指令集:RV32I、RV64I、RV32E和RV64E。其中,RV32I和RV64I都包含32个通用寄存器,位宽分别为32比特和64比特,而RV32E和RV64E则将寄存器数量减少到16个。 对于...
这里要明确两个概念:指令集规范(Specification)和处理器实现(Implementation)是两个不同层次的概念,要区分开。指令集(ISA)是规范标准,往往用一本书或几张纸来记录描述,而处理器实现是基于指令集规范完成的源代码。RISC-V是一个指令集规范。 我们可以基于x86/ARM/ RISC-V指令集,进行处理器微架构设计和实现形成源代...
In this work, we propose an extension of the RISC-V debug specification which enables efficient fault injection testing of the firmware executed on an FPGA-emulated core under a commonly observed instruction skip fault model. We use insights from a fault injection campaign to harden and protect ...
