JTAG DTM - JTAG Debug Transport Module VIP which is compliant to the IEEE 1149-1 specification and RISC-V Debug specification 0.13.2. adds debug support. PLIC - PLIC VIP is advantageous of being able to verify all the Interrupt Controllers (PLIC, CLIC, CLINT), popularly supported in majority...
本书首先介绍 RISC-V 体系结构基础知识、实验环境搭建、基础指令集、函数调用规范与栈,然后讲解 GNU 汇编器、链接器与链接脚本、内嵌汇编代码,接着讨论 RISC-V 体系结构中的异常处理、中断处理与中断控制器、内存管理、高速缓存、缓存一致性、TLB 管理、原子操作、内存屏障指令、合理使用内存屏障指令、与操作系统相关...
支持RV32/64，支持MMU（源码有，图例没展示），CLINT是定时器等软中断，PLIC是中断控制器，还支持DMA和...
The RISC-V QEMU port supports the following hardware blocks and features: HTIF Console (Host Target Interface) for Spike emulation SiFive CLINT (Core Local Interruptor) for Timer interrupts and IPIs SiFive PLIC (Platform Level Interrupt Controller) for multi-core interrupts ...
1.1. Backward Compatibility With SiFive CLINT The RISC-V ACLINT specification is defined to be backward compatible with the SiFive CLINT specification. The register definitions and register offsets of the MTIMER and MSWI devices are compatible with the timer and IPI registers defined by the SiFive...

“core”. Broadly speaking, the number of cores in a given CPU quantifies the number of things it can do at the same time (i.e. in parallel). The RISC-V privileged specification generalizes this concept with the notion of “Hardware Threads” (harts). One of the roles of an ...
