Hyper-threading
Hyper-threading (officially called Hyper-Threading Technology or HT Technology and abbreviated as HTT or HT) is Intel's proprietary simultaneous multithreading (SMT) implementation used to improve parallelization of computations (doing multiple tasks at once) performed on x86 microprocessors. It was introduced on Xeon server processors in February 2002 and on Pentium 4 desktop processors in November 2002. Since then, Intel has included this technology in Itanium, Atom, and Core 'i' Series CPUs, among others. For each processor core that is physically present, the operating system addresses two virtual (logical) cores and shares the workload between them when possible. The main function of hyper-threading is to increase the number of independent instructions in the pipeline; it takes advantage of superscalar architecture, in which multiple instructions operate on separate data in parallel. With HTT, one physical core appears as two processors to the operating system, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium Polymer Battery
A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, such as mobile devices, radio-controlled aircraft and some electric vehicles. History LiPo cells follow the history of lithium-ion and lithium-metal cells which underwent extensive research during the 1980s, reaching a significant milestone with Sony's first commercial cylindrical Li-ion cell in 1991. After that, other packaging forms evolved, including the flat pouch format. Design origin and terminology Lithium polymer cells have evolved from lithium-ion and lithium-metal batteries. The primary difference is that instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual SIM
Some mobile phones support use of two SIM cards, described as dual SIM operation. When a second SIM card is installed, the phone either allows users to switch between two separate mobile network services manually, has hardware support for keeping both connections in a "standby" state for automatic switching, or has individual transceivers for maintaining both network connections at once. Dual SIM phones are mainstream in many countries where phones are normally sold unlocked. Dual SIMs are popular for separating personal and business calls, in locations where lower prices apply to calls between clients of the same provider, where a single network may lack comprehensive coverage, and for travel across national and regional borders. In countries where dual SIM phones are the norm, people who require only one SIM simply leave the second SIM slot empty. Dual SIM phones will usually have two unique IMEI numbers, one for each SIM slot. Devices that use more than two SIM cards have also ...

In-plane Switching
IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (''in-plane''). The molecules are reoriented by an applied electric field, whilst remaining essentially parallel to the surfaces to produce an image. It was designed to solve the strong viewing angle dependence and low-quality color reproduction of the twisted nematic field effect (TN) matrix LCDs prevalent in the late 1980s. History The TN method was the only viable technology for active matrix TFT LCDs in the late 1980s and early 1990s. Early panels showed grayscale inversion from up to down, and had a high response time (for this kind of transition, 1 ms is visually better than 5 ms). In the mid-1990s new technologies were developed—typically IPS and Vertical Alignment (VA)—that could resolve these weaknesse ...

Adreno
Adreno is a series of graphics processing unit (GPU) semiconductor intellectual property cores developed by Qualcomm and used in many of their SoCs. History Adreno (an anagram of AMD's graphic card brand '' Radeon''), was originally developed by ATI Technologies and sold to Qualcomm in 2009 for $65M, and was used in their mobile chipset products. Early Adreno models included the Adreno 100 and 110, which had 2D graphics acceleration and limited multimedia capabilities. At the time, 3D graphics on mobile platforms were commonly handled using software-based rendering engines, which limited their performance. With growing demand for more advanced multimedia and 3D graphics capabilities, Qualcomm licensed the Imageon IP from AMD, in order to add hardware-accelerated 3D capabilities to their mobile products. Further collaboration with AMD resulted in the development of the Adreno 200, originally named the AMD Z430, based on the R400 architecture used in the Xenos GPU of the Xbox 3 ...

Android Lollipop
Android Lollipop (code name, codenamed Android L during development) is the fifth major version of the Android (operating system), Android mobile operating system developed by Google and the 12th version of Android, spanning versions between 5.0 and 5.1.1. Unveiled on June 25, 2014 at the Google I/O 2014 conference, it became available through official Over-the-air programming, over-the-air (OTA) updates on November 12, 2014, for select devices that run distributions of Android serviced by Google (such as Google Nexus, Nexus and Google Play edition devices). Its source code was made available on November 3, 2014. The first phone with Android Lollipop was Nexus 6. One of the most prominent changes in the Lollipop release is a redesigned user interface built around a design language known as Material Design, which was made to retain a paper-like feel to the interface. Other changes include improvements to the notifications, which can be accessed from the lockscreen and displayed wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Android KitKat
Android KitKat is the codename for the eleventh Android mobile operating system, representing release version 4.4. Unveiled on September 3, 2013, KitKat focused primarily on optimizing the operating system for improved performance on entry-level devices with limited resources. The first phone with Android KitKat was the Nexus 5. 1.39% of Android devices run KitKat. it is the oldest Android version still supported by Google Play Services and is currently the minimum version to develop apps for the Google Play Store. History Android 4.4 "KitKat" was officially announced on September 3, 2013. The release was internally codenamed "Key lime pie"; but John Lagerling, director of Android global partnerships, and his team, decided to drop the name, arguing that "very few people actually know the taste of a key lime pie". Aiming for a codename that was "fun and unexpected", his team pursued the possibility of naming the release "KitKat" instead. Lagerling phoned a representative of N ...
