Any mutex Protocol has the following problem: If the lock cannot be obtained, what should we do? There are two options for this. One solution is to let it continue to try. This lock is calledSpin lockThe repeated lock test process is calledRotating or waiting. It is reasonable to select the rotation method when the lock delay is short. However, only rotating in a multi-processor has practical significance. Taslock Code Code highlighting produce

possible. Backup time: it refers to the time when the job arrives at the system and waits for memory to enter in the external storage. The smaller the time, the better. Waiting Time: refers to the time in the ready queue waiting for scheduling to enter the processor. Response time: the time from request submission to First Response output.

graphics interface, which provides up to 4 times times the graphics bandwidth for high-end systems with discrete graphics. With the support of the system manufacturer, you can also obtain options such as TV tuner, Intel High-definition Audio, personal video and remote control, which support Dolby Digital and 7.1 surround sound, while continuing to enjoy the durability battery usage time advantages of Intel Centrino Mobile technology calculations.

SendAsync sends the request to the internal processor.3. The internal processor returns a response message. (This step is asynchronous)4. Process the response and ret

, MIPS32 Second Edition also supports mips-3d. The Mcu:micro-control unit micro-control unit enhances memory-mapped I/O processing and provides lower interrupt latency. MIPS32, MIPS64 all support MCU. 7, MICROMIPS32/64The MICROMIPS32/64 instruction set architecture integrates high-performance code compression technology with 16-bit and 32-bit optimization instructions, maintaining 98% MIPS32 performance, reducing the cost of the chip and reducing system power consumption at the same tim

defined by extensions, so they are different on each platform. Unfortunately, all Android devices only support the Ericsson texture compression (ETC1) format (except for the first generation devices, the first generation devices do not support OpenGL ES 2.0 ). ETC1 only supports 8-bit precision per pixel, and does not support alpha. Most games use compressed textures with alpha, which is a serious obstacle to porting. The Android platform that does not support alpha may use several specialized

encoded into the instruction. When a condition mnemonic is not present, the defalt behavior is to set it to always execute. Pipeline: Using a pipeline speeds up execution by fetching the next instruction while other instructions are being decoded and executed. Pipeline executing characteristics: 1. The pipeline has not processed an instruction until it passes completely through the execute stage. 2. program counter (PS) alway points to the address
