Abstract

The invention discloses a memory access method and a memory address allocation method and device, and belongs to the technical field of information. The method comprises the steps that a computer device obtains a memory access request, the memory access request comprises target memory address information, the target memory address information comprises an address bit and a length bit, the address bit is used for carrying a target address of an accessed memory, and the length bit is used for carrying the length of the memory allowed to be accessed from a set address; and the computer equipment accesses the memory based on the memory access request. According to the method, the address bit and the length bit are set in the target memory address information, so that the computer equipment can access the memory according to the target address of the memory and the length of the memory, the functions of the memory address information are enriched, and the memory address information is fully and efficiently utilized.

Description

technical field [0001] The present application relates to the field of information technology, and in particular, to a memory access method, a memory address allocation method, and an apparatus. Background technique [0002] Computer equipment generally includes a central processing unit (Central Processing Unit, CPU), memory and software. The CPU can access memory through the bus. [0003] When the CPU accesses the memory, it sends a memory access request (such as a read request or a write request) to the memory through a bus, and the memory access request includes memory address information. For example, in a computer device that supports a 64-bit instruction set architecture (Architecture64, Arch64), the total length of the memory address information is 64 bits. Due to the requirement of actual memory space and the limitation of hardware conditions, the lower 48 bits of the 64 bits are usually used. bit to carry the accessed memory address, that is, the lower 48 bits ar...
