Abstract: A method for managing micro-operations is provided. The method includes determining whether a translation buffer and a micro-operation cache store a micro-operation corresponding to a translation instruction using a processing unit, when the processing unit executes the translation instruction. The method includes outputting a certain micro-operation to enter a system management mode using the processing unit, when the translation buffer and the micro-operation cache don’t store the micro-operation corresponding to the translation instruction. The method includes translating the translation instruction into the micro-operation corresponding to the translation instruction in the system management mode using the processing unit.

Abstract: A storage device is provided. The storage device includes a control unit, a hot spare area, and a data area. Because a quantity of bits that can be stored in a second-level storage unit corresponding to the hot spare area is less than a quantity of bits that can be stored in a first-level storage unit corresponding to the data area, data read/write performance of the hot spare area is higher than data read/write performance of the data area. In a data access process, the storage device temporarily stores target data in the hot spare area, and a data read/write speed of the storage device is consistent with a data read/write speed of the hot spare area. This improves data access efficiency of the storage device.

Abstract: This application relates to the field of image processing technologies, and provides an image presentation method, an electronic device, a storage medium, and a chip. The method may include: After an upper-layer application completes drawing a buffer, SurfaceFlinger (SF) does not need to wait for a Vsync signal, but immediately composes the buffer drawn by the upper-layer application, and a display driver sends the composed buffer to a display for display after receiving the Vsync signal. To avoid accumulation of the composed buffer, the method may further include: After the upper-layer application completes drawing the buffer, when a composed buffer has not yet been displayed, the SF stops a current composition and disables the Vsync signal sent to the SF. In addition, the SF takes the latest buffers for composition and discards the older buffers when composing buffers.

Abstract: The present invention relates to a method for a processor and a computer system to enter system management mode (SMM). The method is applied to the processor, which includes at least one logical core. The method includes entering the SMM in response to a system management interrupt (SMI), storing current state information to a corresponding state save area; setting operation mode to target operating mode, and executing the SMI handler under the target operating mode. The address of the state save area, the address of the core configuration information memory space, and the address of the SMI handler can be determined directly. Each logical core may enter the target operating mode directly through hardware setting every time after entering the SMM, and thus does not need to perform a fixed operation of mode switching when executing the SMI handler, which may improve the execution efficiency of the SMI handler.

Abstract: The present application relates to the technical field of system management mode (SMM), and in particular it relates to a control method, a processor, and a computer system for system management mode. The method is applied to a processor. The processor includes at least one logical core. The method performs an initialization setting before each logical core enters system management mode.
