The emulator's environment interface has been updated to facilitate page lookup instead of specific fetches. Additionally, a preliminary cache for fetches has been implemented, which encompasses both MMU and physical page lookups. This enhancement boosts performance. This approach, which includes bypassing the PTE bit set operation in the cache, should be compliant with RISC-V standards. It allows MMU lookups to be carried out speculatively, adhering to the architecture's guidelines.
