HiFive1开发板驱动mtime的时钟频率是32768Hz,那么需要17851025年mtime才会溢出。 RV64I或RV128I访问mtime或mtimecmp只需要一条指令,不会有什么问题。RV32I/RV32E访问mtime或mtimecmp需要把这两个寄存器拆成两个32位寄存器来访问,这需要两条指令,如果真好碰上低32位要进位的情况,那么就会产生问题,访问的结果会产生...
是的,RISC-V的基础整数指令集(rv32i)是已经冻结的。这意味着这部分指令集是稳定的,不会再有更改或添加新的指令。冻结指令集有助于确保硬件和软件之间的兼容性和稳定性。 填充括号,给出完整答案: risc-v基础部分(rv32i)只有47条指令,并已冻结。 由于这个问题主要是关于RISC-V指令集的基础信息,并不需要代码片...

PicoRV32 is a CPU core that implements the RISC-V RV32IMC Instruction Set. It can be configured as RV32E, RV32I, RV32IC, RV32IM, or RV32IMC core, and optionally contains a built-in interrupt controller.Tools (gcc, binutils, etc..) can be obtained via the RISC-V Website. T...
The library supports RV32I, as well as the newly introduced RV32E embedded variant of the RISC-V core with the assembly-level code. "This new release is much smaller than anything available to us for comparison and, at the same time, is incredibly fast,” says Rolf Segger, Founder of ...
