在商用超标量乱序 CPU 问世之前,业界广泛采用标量流水线顺序执行架构,CPU 的 IPC(Instructions Per Cycle)始终小于 1,这很快成为了高速处理器的性能瓶颈。为了突破瓶颈,业界提出了很多提高 IPC 的技术,包括“VLIW(超长指令字)”、“向量处理器”和“多处理器”等。但等到 80 年代中后期市场上正式出现超标量产品后...
A Central Processing Unit (CPU) is a fundamental component in computing, acting as the brain of a computer. It executes instructions from computer programs and processes data. Present in devices ranging from desktops and servers to smartphones, CPUs play a crucial role in modern technology. The ...

Superscalar means executing multiple instructions at the same time while chip-level multithreading (CMT) executes instructions from multiple threads within one processor chip at the same time. There are many ways to support more than one thread within a chip, namely: Interleaved multithreading: Interle...
AVX instructions can cause significant heat and power draw. Setting an AVX offset can help maintain stability: In BIOS, locate the AVX offset setting. Set a negative offset (e.g., -2 or -3) to reduce clock speeds during AVX workloads. ...

Multi-core processors:Multi-core processors are integrated circuits equipped with at least two processor cores, so they can deliver supreme performance while using less energy. What are threads? Threads can be thought of as virtual sequences of instructions that are issued to a CPU. Primarily, th...
32 SP FLOPs/cycle: two 8-wide FMA (fused multiply-add) instructions AMD K10: 4 DP FLOPs/cycle: 2-wide SSE2 addition + 2-wide SSE2 multiplication 8 SP FLOPs/cycle: 4-wide SSE addition + 4-wide SSE multiplication AMD Bulldozer/Piledriver/Steamroller/Excavator, per module (two cores): ...
When no instructions are ready to execute, Windows will put a processor into a target idle state (or C-State), as determined by the Windows Power Manager. Based on CPU usage patterns, a processor’s target C-state will be adjusted over time....
Thanks for the detailed guidance on retrieving per-core CPU usage in Azure VMs through the Azure Portal's Monitoring tools. Your step-by-step instructions will be beneficial. Regarding the distinction between CPU usage and per-core CPU usage, your explanation clarifies the difference for me. It...
