Microarchitecture
In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. A given ISA may be implemented with different microarchitectures; implementations may vary due to different goals of a given design or due to shifts in technology. Computer architecture is the combination of microarchitecture and instruction set architecture. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the instructions, execution model, processor registers, address and data formats among other things. The microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usu ...

CPU Cache
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I- or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM. Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (M ...

Intel Developer Forum
The Intel Developer Forum (IDF) was a biannual gathering of technologists to discuss Intel products and products based on Intel products. The first IDF was held in 1997. To emphasize the importance of China, the Spring 2007 IDF was held in Beijing instead of San Francisco, and San Francisco and Taipei shared the Fall IDF event in September and October, respectively. Three IDF shows were scheduled in 2008; with the date of IDF San Francisco notably moving to August rather than September. In previous years, events were held in major cities around the world such as San Francisco, Mumbai, Bangalore, Moscow, Cairo, São Paulo, Amsterdam, Munich and Tokyo. On April 17, 2017, Intel announced that it would no longer be hosting IDF. As a result of this announcement, IDF17, which was scheduled for August in San Francisco, was canceled. 2007 events * April 17–18, 2007 – Beijing, China * September 18–20, 2007 – San Francisco, United States * October 15–16, 2007 – Taipei, Taiwan ...

AMD Threadripper
Threadripper, or Ryzen Threadripper, is a brand of HEDT (high-end desktop) and workstation multi-core x86-64 microprocessors designed and marketed by Advanced Micro Devices (AMD), and based on the Zen microarchitecture. It consists of central processing units (CPUs) marketed for mainstream and workstation segments, and as such comes in two line-ups, Threadripper and Threadripper PRO respectively. Background Threadripper, which is geared for high-end desktops (HEDT) and workstations, was not developed as part of a business plan or a specific roadmap. Instead, a small team inside AMD saw an opportunity to give AMD the lead in desktop CPU performance. After some progress was made in their spare time, the project was greenlit and put in an official roadmap by 2016. Characteristics Threadripper chips have higher core counts, increased power requirements, support faster memory, and more expansion opportunities. The Zen 4 core's pipelines use a high-density leading-edge 5 nm process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Simultaneous Multithreading
Simultaneous multithreading (SMT) is a technique for improving the overall efficiency of superscalar CPUs with hardware multithreading. SMT permits multiple independent threads of execution to better use the resources provided by modern processor architectures. Details The term ''multithreading'' is ambiguous, because not only can multiple threads be executed simultaneously on one CPU core, but also multiple tasks (with different page tables, different task state segments, different protection rings, different I/O permissions, etc.). Although running on the same core, they are completely separated from each other. Multithreading is similar in concept to preemptive multitasking but is implemented at the thread level of execution in modern superscalar processors. Simultaneous multithreading (SMT) is one of the two main implementations of multithreading, the other form being temporal multithreading (also known as super-threading). In temporal multithreading, only one thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
