Abstract
A memory access processing method and apparatus, and a system. The method includes receiving a memory access request sent by a processor, combining multiple memory access requests received within a preset time period to form a new memory access request, where the new memory access request includes a code bit vector corresponding to memory addresses. A first code bit identifier is configured for the code bits that are in the code bit vector and corresponding to the memory addresses accessed by the multiple memory access requests. The method further includes sending the new memory access request to a memory controller, so that the memory controller executes a memory access operation on a memory address corresponding to the first code bit identifier. The method effectively improves memory bandwidth utilization.
