Abstract: In a data access method, after an interface card receives a first data write instruction or a first data read instruction, the interface card generates a second data write instruction or a second data read instruction, and writes the second data write instruction or the second data read instruction into a cache. No resource of a processor of a storage device is used. After the interface card writes the second data write instruction or the second data read instruction into the cache, a cache control unit sends the second data write instruction or the second data read instruction to a storage subsystem. No resource of the processor of the storage device is used. Alternatively, the cache control unit may instruct the storage subsystem to execute the second data write instruction or the second data read instruction.

Abstract: A computer device and a memory startup method of a computer are provided, where a basic input/output system initializes only a first part of memory in a memory initialization phase after a computer is powered on and started, so that an operating system can be started, and after the operating system is started, the basic input/output system continues to initialize memory that is not initialized in the computer, so that, in a startup phase, the computer can start the operating system without needing to wait until all memory has been initialized; therefore, a time from being started to entering the operating system is reduced for the computer, and a user can quickly enter the operating system to perform an operation, thereby improving user experience.

Abstract: A method, device, and system for implementing hardware acceleration processing, where the method includes memory mapping input/output (MMIO) processing being performed on a data buffer address of a hardware acceleration processor in order to obtain an address in addressing space of a central processing unit (CPU). In addition, a network adapter has a remote direct memory access (RDMA) or a direct memory access (DMA) function. Alternatively, a network adapter of a hardware acceleration device can directly send received data on which the hardware acceleration processing is to be performed to a hardware acceleration processor. In this way, resource consumption is reduced when the CPU of a computer device receives and forwards the data on which the hardware acceleration processing is to be performed, and in addition, storage space of a memory of the computer device is saved.
