LeapFrog Epic
The LeapFrog Epic (styled as LeapFrog epic) is an Android-based mini-tablet computer produced and marketed by LeapFrog Enterprises. Released in 2015, the Epic is LeapFrog's first device to run on Android; most of LeapFrog's mobile computing devices for children run on a customized Ångström Linux distribution. Name Despite being sold alongside the LeapPad Explorer line of tablets, the original Epic and Academy Edition variants are not marketed as a LeapPad model and is instead referred to in official literature as the ''LeapFrog'' Epic, the latter moniker being a backronym for "explore, play, imagine and create", in reference to the Epic's educational nature. Features Hardware The Epic has a TFT-LCD touchscreen, Wi-Fi capability, a 1.3 GHz ARM Cortex-A7 MediaTek MT8127 processor, a 2.0 MP rear-facing camera and a 2.0 MP front-facing camera. As with other devices and toys marketed by the company, the Epic is aimed for children ages 3–9, and like the lower-end LeapPa ...

Mali (GPU)
The Mali series of graphics processing units (GPUs) and multimedia processors are semiconductor intellectual property cores produced by Arm Holdings for licensing in various ASIC designs by Arm partners. Mali GPUs were developed by Falanx Microsystems A/S, which was a spin-off of a research project from the Norwegian University of Science and Technology. Arm Holdings acquired Falanx Microsystems A/S on June 23, 2006 and renamed the company to Arm Norway. Originally named ''Malaik'', the team shortened the name to ''Mali'', Serbo-Croatian for "small", which was thought to be fitting for a mobile GPU. Technical details Like other embedded IP cores for 3D rendering acceleration, the Mali GPU does not include display controllers driving monitors, in contrast to common desktop video cards. Instead, the Mali ARM core is a pure 3D engine that renders graphics into memory and passes the rendered image over to another core to handle display. ARM does, however, license display cont ...

ARM Cortex-A7
The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011. Overview It has two target applications; firstly as a smaller, simpler, and more power-efficient successor to the Cortex-A8. The other use is in the big.LITTLE architecture, combining one or more A7 cores with one or more Cortex-A15 cores into a heterogeneous system. To do this it is fully feature-compatible with the A15. Key features of the Cortex-A7 core are: * Partial dual-issue, in-order microarchitecture with an 8-stage pipeline * NEON SIMD instruction set extension * VFPv4 Floating Point Unit * Thumb-2 instruction set encoding * Jazelle RCT * Hardware virtualization * Large Page Address Extensions (LPAE) * Integrated level 2 Cache (0–1 MB) * 1.9 DMIPS / MHz * Typical clock speed 1.5 GHz Chips Several system-on-chips (SoC) have implemented the Cortex-A7 core, including: * Allwinner A20 (dual-core A7 + Mali-400 MP2 GPU) ...

TFT-LCD
A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in appliances including television sets, computer monitors, mobile phones, handheld devices, video game systems, personal digital assistants, navigation systems, projectors, and dashboards in automobiles. History In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark's ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. An acronym is a word derived from the initial letters of the words of a phrase, such as ''radar'' from "''ra''dio ''d''etection ''a''nd ''r''anging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin." Many fictional espionage organizations are backronyms, such as SPECTRE (''sp''ecial ''e''xecutive for ''c''ounterintelligence, ''t''errorism, ''r''evenge and ''e''xtortion) from the James Bond franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl who was abducted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ångström Distribution
The Ångström distribution is a defunct Linux distribution for a variety of embedded devices. The distribution is the result of work by developers from the OpenZaurus, OpenEmbedded, and OpenSIMpad projects. The graphical user interfaces (GUIs) available are OPIE and GPE among other options. The Ångström distribution is in "competition" witPoky Linux Ångström is based on the OpenEmbedded project, specifically the OpenEmbedded-Core (OE-Core) layer. While both Ångström and Poky Linux are based on OE-Core, mostly utilize the same toolchain and are both officially "Yocto compatible", only Poky Linux is officially part of the Yocto Project. Ångström primarily differs from Poky Linux in being a binary distribution (like e.g. the Debian, Fedora, OpenSuse or Ubuntu Linux distributions), using opkg for package management. Hence an essential part of Ångström builds is binary package feed allowing to simply install software distributed as opkg packages, without having t ...

Pixel Density
Pixels per inch (ppi) and pixels per centimetre (ppcm or pixels/cm) are measurements of the pixel density of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner. Horizontal and vertical density are usually the same, as most devices have square pixels, but differ on devices that have non-square pixels. Note that pixel density is not the same as where the former describes the amount of detail on a physical surface or device, the latter describes the amount of pixel information regardless of its scale. Considered in another way, a pixel has no inherent size or unit (a pixel is actually a sample), but when it is printed, displayed, or scanned, then the pixel has both a physical size (dimension) and a pixel density (ppi). Basic principles Since most digital hardware devices use dots or pixels, the size of the media (in inches) and the number of pixels (or dots) are directly related by the 'pixels per ...

Aspect Ratio (image)
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as ''16:9'', sixteen-to-nine. For the ''x'':''y'' aspect ratio, the image is ''x'' units wide and ''y'' units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography. Some common examples The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1.The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the American Society of Cinematographers' ''American Cinematographer Manual'' (Many widescreen films before the 1970 SMPTE revision used 2.35:1). Two common videographic aspect ratios are 4:3 (1.:1), the universal video format of the 20th century, and 16:9 (1.:1), universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently. In still camera photography, the most common aspect ra ...

Pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.
