CPU有很多硬件提升手段,其中较为常见的是超标量(superscalar)、流水线(pipelining)、超线程(Hyper-Threading)、多核(multi-core)、SIMD等,通常较难理解,本文以洗衣服为例尝试通俗理解这些概念. 假如把一个线程任务模拟成洗衣机器操作,那一个线程包含多个指令(处理上衣、处理裤子、处理袜子...),一个指令又包含多个周...

Multithreadingcomputercentral processing unitshave hardware support to efficiently execute multiplethreads. These are distinguished frommultiprocessingsystems (such asmulti-coresystems) in that the threads have to share the resources of a single core: the computing units, theCPU cachesand thetranslation looka...

multicorecpu（多核心处理器）可以同时执行多个线程，从而提高计算机的性能。若操作系统、应用程序和开发环境都能充分利用多核心处理器的优点，那么开启多核心处理器可以大幅提高计算机的性能和响应速度。在现代操作系统和许多应用程序都能很好地利用多核心cpu。例如，当您运行多个程序或任务时，多核心cpu可以将...
To test the CPU, it executes complex calculations involving integers and floating-point numbers. For the GPU test, it runs six 3D game simulations. RAM tests measure multi-core bandwidth and latency, while drive tests involve performing numerous read, write, and mixed IO operations. ...
