Zen (first Generation)
Zen is the codename for the first iteration in a family of computer processor microarchitectures of the same name from AMD. It was first used with their Ryzen series of CPUs in February 2017. The first Zen-based preview system was demonstrated at E3 2016, and first substantially detailed at an event hosted a block away from the Intel Developer Forum 2016. The first Zen-based CPUs, codenamed "Summit Ridge", reached the market in early March 2017, Zen-derived Epyc server processors launched in June 2017 and Zen-based APUs arrived in November 2017. Zen is a clean sheet design that differs from AMD's previous long-standing Bulldozer architecture. Zen-based processors use a 14 nm FinFET process, are reportedly more energy efficient, and can execute significantly more instructions per cycle. SMT has been introduced, allowing each core to run two threads. The cache system has also been redesigned, making the L1 cache write-back. Zen processors use three different sockets: desktop and ...

Steam Deck
The Steam Deck is a handheld gaming computer developed by Valve Corporation. Released on February 25, 2022, the Steam Deck can be played as a handheld or connected to a monitor in the same manner as the Nintendo Switch. It is an x86-64-v3 device with integrated gaming inputs designed to play the full Steam library, including Windows PC games via the Linux-based Proton compatibility layer. The system is an open platform, allowing users to install other compatible games on the device or other operating systems. History Valve's first foray into hardware was with the Steam Machine, a computer specification based on the Linux-derived SteamOS that could be adopted by any computer manufacturer to make systems optimized for running Steam and games from it. Introduced in 2015, the platform did not sell well and Valve quietly pulled back on it by April 2018, but stated they remained committed to providing some type of open-hardware platform. Steam Deck designer Scott Dalton said "there w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instructions Per Clock
In computer architecture, instructions per cycle (IPC), commonly called instructions per clock is one aspect of a processor's performance: the average number of instructions executed for each clock cycle. It is the multiplicative inverse of cycles per instruction. John L. Hennessy, David A. Patterson.Computer architecture: a quantitative approach. 2007. Explanation While early generations of CPUs carried out all the steps to execute an instruction sequentially, modern CPUs can do many things in parallel. As it is impossible to just keep doubling the speed of the clock, instruction pipelining and superscalar processor design have evolved so CPUs can use a variety of execution units in parallel - looking ahead through the incoming instructions in order to optimise them. This leads to the ''instructions per cycle completed'' being much higher than 1 and is responsible for much of the speed improvements in subsequent CPU generations. Calculation of IPC The calculation of IPC is ... [...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 thread of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Input/output
In computing, input/output (I/O, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. Any interaction with the system by a interactor is an input and the reaction the system responds is called the output. The designation of a device as either input or output depends on perspective.

Chiplets
A chiplet is a tiny integrated circuit (IC) that contains a well-defined subset of functionality. It is designed to be combined with other chiplets on an interposer in a single electronic packaging, package. A set of chiplets can be implemented in a mix-and-match "LEGO-like" assembly. This provides several advantages over a traditional system on a chip, system on chip (SoC): * Reusable IP (Intellectual Property): the same chiplet can be used in many different devices * Heterogeneous integration: chiplets can be fabricated with different processes, materials, and Node, nodes, each optimized for its particular function * Known good die: chiplets can be tested before assembly, improving the yield of the final device Multiple chiplets working together in a single integrated circuit may be called a multi-chip module (MCM), hybrid integrated circuit, hybrid IC, 2.5D integrated circuit, 2.5D IC, or an Advanced packaging (semiconductors), advanced package. Chiplets may be connected with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectre (security Vulnerability)
Spectre refers to one of the two original transient execution CPU vulnerabilities (the other being Meltdown), which involve microarchitectural timing side-channel attacks. These affect modern microprocessors that perform branch prediction and other forms of speculation. On most processors, the speculative execution resulting from a branch misprediction may leave observable side effects that may reveal private data to attackers. For example, if the pattern of memory accesses performed by such speculative execution depends on private data, the resulting state of the data cache constitutes a side channel through which an attacker may be able to extract information about the private data using a timing attack. Two Common Vulnerabilities and Exposures IDs related to Spectre, (bounds check bypass, Spectre-V1, Spectre 1.0) and (branch target injection, Spectre-V2), have been issued. JIT engines used for JavaScript were found to be vulnerable. A website can read data stored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computex
COMPUTEX Taipei, or Taipei International Information Technology Show (), is a computer expo held annually in Taipei, Taiwan. Since the early 2000s, it is one of the largest computer and technology trade shows in the world. The last COMPUTEX was held from 28 May to 1 June 2019 with sessions about such topics as 5G, facial recognition, and Internet of Things, along with a charity League of Legends tournament. COMPUTEX 2020 was cancelled after a delay from early June to 28 September due to public health safety concerns of the COVID-19 pandemic. COMPUTEX is co-organized by government-funded Taiwan External Trade Development Council (TAITRA) and private sector Taipei Computer Association (TCA). The first expo, then called Taipei Computer Show, was held in 1981 and started out as a place where small and medium-sized businesses in Taiwan's nascent computer industry could display their products.
