Abstract
A memory state recovery method for a no-MMU environment in emulated CPU chip acceleration includes relocation of a virtual memory area, which involves performing relocation on each virtual memory area in an available physical memory space, converting a base address, which is represented by a virtual address of the virtual memory area, into a physical address, and keeping the length of the address unchanged. The method also includes recovery of memory access data, wherein for each memory access read record, a recovery rule for a storage position is the base address after relocation of the virtual memory area plus an offset; recovery of a stack state, wherein for each stack frame, a recovery rule for a storage position is the base address after relocation of the virtual memory area plus an offset; and recovery of the value of a general register.
