Webb13 juni 2024 · I’ve fixed two more bugs in the RISC-V emulator recently, both related to memory paging . The first one was caused by only supporting a one third of the possible page faults, the second one was closely related to page faults as well. Load / store / fetch page faults Virtual memory with its page table allows the operating system to store a … WebbRV64I is the base integer instruction set for the 64-bit architecture, which builds upon the RV32I variant. RV64I shares most of the instructions with RV32I but the width of registers is different and there are a few additional instructions only in RV64I. The base integer instruction set has 47 instructions (35 instructions from RV32I and 12 ...
