DESCRIPTION:Memory Protection Tables (MPT) is an emerging RISC-V extension 
 under community discussion that enables fine-grained multi-supervisor doma
 in physical memory isolation and access control for multi-tenant computing
 \, addressing the security and isolation limitations of the traditional PM
 P mechanisms. This work presents the first open-source hardware implementa
 tion of the MPT draft specification (v0.4). Our design features a multi-le
 vel cache for accelerated permission checking and an L1TLB extension to re
 duce query frequency\, with a decoupled architecture for portability. Eval
 uation shows only 2.32\\% average SPEC06 performance overhead and a 0.244\
 \% core area overhead\, providing a hardware reference for SMMPT standardi
 zation.
