2. (微)架构:CPU对更定指令集的处理是依赖于它内部的一系列组件,例如指令提取(fetch)、指令解码(decode)、指令分发(issue/dispatch)、分支预测(branch predictor)、寄存器表(register file)、运算单元(ALU)、访存单元(LSU)、各类缓存(buffers/queues/caches),例如图4是UCB团队提出的RISCV乱序执行处理器SonicBOOM[2...
Even the new power management (a.ka. Turbo Boost) will have a far bigger effect on performance than, say, changes in the branch predictor.rnI'm a CPU guy from way back, and I spent the 1990s writing about superscalar instruction issue and drawing pipeline diagrams for Microprocessor Report....
And yet mispredictions do happen (sometimes C comes along instead of B, although the branch predictor remembers full well that A is normally followed by B). If you train the system long enough by demonstrating that a certain branch is the right one and is always executed and then change a...

What is a capital market?Financial MarketsFinancial Markets can be defined as the markets where the sale and purchase of securities and money-related instruments take place. These markets direct the excess funds into investment opportunities. Examples of financial markets are the stock market and ...
Decision treesare classification models that partition data into subsets based on categories of input variables. This helps you understand someone's path of decisions. A decision tree looks like a tree with each branch representing a choice between a number of alternatives, and each leaf representing...
Arithmetic is a branch of mathematics. Arithmetic includes different mathematical operations such as addition, subtraction, multiplication and division. Learn the basics of arithmetic with examples at BYJU’S.

High-grade, soft-tissue sarcomas in deep locations may have a poorer prognosis regarding local recurrence than low-grade sarcomas or those located superficially. Although previous reports evaluated tumors at various depths, it is unclear what factors influence recurrence of deep, high-grade sarcomas....
branch corresponds to a possible value of that variable. The goal of a decision tree model is to predict the value of a target variable based on the values of the predictor variables. The model uses the tree structure to determine the most likely outcome for a given set of predictor ...
