Abstract: Example data transmission methods, processor systems, and memory access systems are provided. One example processor system is applied to a source end device. The processor system includes a processor core and a first remote direct memory access (RDMA) network interface card. The processor core is configured to deliver a memory write instruction. The memory write instruction includes to-be-written data and a destination address of the to-be-written data. The destination address is a memory address of a destination end device. The first RDMA network interface card is configured to encapsulate the to-be-written data based on the destination address of the to-be-written data and configuration information of the destination end device and send the encapsulated to-be-written data to a second RDMA network interface card of the destination end device.
