Direct memory access (DMA) is a feature of computer systems and allows certain hardware subsystems to access main system memory independently of the central processing unit (CPU).. Without DMA, when the CPU is using programmed input/output, it is typically fully occupied for the entire duration of the read or write operation, and is thus unavailable to perform other work.

The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred …

Windows NT 3.1 is the first major release of the Windows NT operating system developed by Microsoft, released on July 27, 1993.. At the time of Windows NT's release, Microsoft's Windows 3.1 desktop environment had established brand recognition and market share; but Windows 3.1 relied on the DOS operating system for essential functions, and it had a constrictive 16-bit …

In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines. A multiplexer of inputs has select lines, which are used to select which ...

The Super FX is a coprocessor on the Graphics Support Unit (GSU) added to select Super Nintendo Entertainment System (SNES) video game cartridges, primarily to facilitate advanced 2D and 3D graphics.The Super FX chip was designed by Argonaut Games, who also co-developed the 3D space rail shooter video game Star Fox with Nintendo to demonstrate the …

The first production system designed as a cluster was the Burroughs B5700 in the mid-1960s. This allowed up to four computers, each with either one or two processors, to be tightly coupled to a common disk storage subsystem in order to distribute the workload. Unlike standard multiprocessor systems, each computer could be restarted without ...

Un système sur une puce, souvent désigné dans la littérature scientifique par le terme anglais « system on a chip » (d'où son abréviation SoC), est un système complet embarqué sur un seul circuit intégré (« puce »), pouvant comprendre de la mémoire, un ou plusieurs microprocesseurs, des périphériques d'interface, ou tout autre ...

The first game, Star Fox, or Starwing in Europe and Australia, was released for the Super Nintendo Entertainment System in 1993. Developed by Nintendo EAD and programmed by Argonaut Software, it uses the Super FX chip to provide 3D graphics during a period of predominately 2D games. Fox McCloud and his team, Slippy Toad, Peppy Hare, and Falco …

Atom is a system on a chip (SoC) platform designed for smartphones and tablet computers, launched by Intel in 2012. It is a continuation of the partnership announced by Intel and Google on September 13, 2011 to provide support for the Android operating system on Intel x86 processors. This range competes with existing SoCs developed for the smartphone and tablet market from …

The Microchip HCS301 was once the most widely used system on garage and gate remote control and receivers. The chip uses the KeeLoq algorithm. The HCS301 KeeLoq system transmits 66 data bits. 34 bits are not encrypted : a 28-bit serial number, 4 bits of button information, and 2 status bits (repeat and low battery indicators).

A chip log, also called common log, ship log, or just log, is a navigation tool mariners use to estimate the speed of a vessel through water. The word knot, to mean nautical mile per hour, derives from this measurement method. ... such as those from the Global Positioning System . However, most commercial GPS systems are not configured to ...

In taxonomy, binomial nomenclature ("two-term naming system"), also called binominal nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.Such a name …

Overview. Non-volatile memory is typically used for the task of secondary storage or long-term persistent storage. The most widely used form of primary storage today is a volatile form of random access memory (RAM), meaning that when the computer is shut down, anything contained in RAM is lost. However, most forms of non-volatile memory have limitations that …
