ePMP

Concept

ePMP, or Enhanced Physical Memory Protection, is a RISC-V memory-protection feature associated with PMP. The provided evidence describes PMP and ePMP as mechanisms that restrict access to memory regions to enforce privilege, isolation, and security policies, and identifies ePMP as a target of directed RISC-V verification suites.

Definition

ePMP stands for Enhanced Physical Memory Protection. In the provided evidence, it is discussed together with Physical Memory Protection (PMP) as a RISC-V feature used to restrict access to memory regions in order to enforce privilege, isolation, and security policies. [C1]
