Memory access processing method and device

The invention discloses a memory access processing method. The memory access processing method comprises the following steps: partitioning a memory area into a low area and a high area according to a preset rule; building a fixed translation lookaside buffer (TLB) mapping entry corresponding to the low area and a dynamic TLB mapping entry corresponding to the high area in a TLB table entry, wherein the dynamic TLB mapping entry is used for replacing a mapping relationship according to a preset page table; and when a memory access request of a preset interface function is received, accessing a memory address of the low area according to the fixed TLB mapping entry, and accessing a memory address of the high area according to the dynamic TLB mapping entry. The invention also discloses a memory access processing device. Through adoption of the memory access processing method and device, the memory access performance of a system is enhanced, and the occupancy rate of a CPU (Central Processing Unit) is reduced. 本发
