Sv48

Concept

Sv48 is a RISC-V virtual memory scheme that uses 48-bit virtual addresses and defines a multi-level page-table structure for address translation. In RISC-V verification, Sv48 page-table walks are a directed-test target, including through ImperasTS-MMU suites for virtual-memory features.

Overview

Sv48 is a RISC-V virtual memory scheme. Alongside Sv39, it is identified as one of the RISC-V virtual-memory modes used for address translation; Sv48 specifically uses 48-bit virtual addresses. These schemes define multi-level page-table structures for translating virtual addresses. [Sv48 definition]
