Transmeta
Transmeta Corporation was an American fabless semiconductor company based in Santa Clara, California. It developed low power x86 compatible microprocessors based on a VLIW core and a software layer called Code Morphing Software. Code Morphing Software (CMS) consisted of an Interpreter (computing), interpreter, a runtime system and a Binary translation#Dynamic binary translation, dynamic binary translator. x86 instructions were first interpreted one instruction at a time and profiled, then depending upon the frequency of execution of a code block, CMS would progressively generate more optimized translations. The VLIW core implemented features specifically designed to accelerate CMS and translations. Among the features were support for general speculation, detection of memory aliasing and detection of self modifying x86 code. The combination of CMS and the VLIW core allowed for the achievement of full x86 compatibility while maintaining performance and reducing power consumption. ...

Efficeon
The Efficeon processor is Transmeta's second-generation 256-bit VLIW design released in 2004 which employs a software engine Code Morphing Software (CMS) to convert code written for x86 processors to the native instruction set of the chip. Like its predecessor, the Transmeta Crusoe (a 128-bit VLIW architecture), Efficeon stresses computational efficiency, low power consumption, and a low thermal footprint. Processor Efficeon most closely mirrors the feature set of Intel Pentium 4 processors, although, like AMD Opteron processors, it supports a fully integrated memory controller, a HyperTransport IO bus, and the NX bit, or no-execute x86 extension to PAE mode. NX bit support is available starting with CMS version 6.0.4. Efficeon's computational performance relative to mobile CPUs like the Intel Pentium M is thought to be lower, although little appears to be published about the relative performance of these competing processors. Efficeon came in two package types: a 783- and a 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Translation
In computing, binary translation is a form of binary recompilation where sequences of instructions are translated from a ''source'' instruction set to the ''target'' instruction set. In some cases such as instruction set simulation, the target instruction set may be the same as the source instruction set, providing testing and debugging features such as instruction trace, conditional breakpoints and hot spot detection. The two main types are static and dynamic binary translation. Translation can be done in hardware (for example, by circuits in a CPU) or in software (e.g. run-time engines, static recompiler, emulators). Motivation Binary translation is motivated by a lack of a binary for a target platform, the lack of source code to compile for the target platform, or otherwise difficulty in compiling the source for the target platform. Statically-recompiled binaries run potentially faster than their respective emulated binaries, as the emulation overhead is removed. This ...

LongRun
LongRun and LongRun2 are power management technologies introduced by Transmeta. LongRun was introduced with the Crusoe processor, while LongRun2 was introduced with the Efficeon processor. LongRun2 has since been licensed to Fujitsu, NEC, Sony, Toshiba, and NVIDIA Nvidia CorporationOfficially written as NVIDIA and stylized in its logo as VIDIA with the lowercase "n" the same height as the uppercase "VIDIA"; formerly stylized as VIDIA with a large italicized lowercase "n" on products from the mid 1990s to .... LongRun automatically adjusted the processor, moving between higher performance but higher power, and lower power but lower performance. The goals of the automation could be adjusted. One control offered processor frequency levels, and the ability to set a minimum and maximum "window", where the automatic controls would not adjust the speed outside of the window. A second control offered a target of either "economy" or "performance". Some versions offered a third con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Very Long Instruction Word
Very long instruction word (VLIW) refers to instruction set architectures designed to exploit instruction level parallelism (ILP). Whereas conventional central processing units (CPU, processor) mostly allow programs to specify instructions to execute in sequence only, a VLIW processor allows programs to explicitly specify instructions to execute in parallel. This design is intended to allow higher performance without the complexity inherent in some other designs. Overview The traditional means to improve performance in processors include dividing instructions into substeps so the instructions can be executed partly at the same time (termed ''pipelining''), dispatching individual instructions to be executed independently, in different parts of the processor (''superscalar architectures''), and even executing instructions in an order different from the program (''out-of-order execution''). These methods all complicate hardware (larger circuits, higher cost and energy use) because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, do what other personal computers do, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops which have traditionally run off operating systems usually designed for desktops, tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subnotebook
Subnotebook, also called ultraportable, superportable, or mini notebook, was a marketing term for laptop computers that are smaller and lighter than a typical notebook-sized laptop. Types and sizes As typical laptop sizes have decreased over the course of the 2010s, and other distinguishing features have become mainstream, the distinction between regular-size and 'subnotebook' laptops has largely disappeared. To the extent that it still exists, 'subnotebook' could be defined as machines with screen smaller than 13" but with a permanently-attached keyboard intended for two-handed typing. Prior to this convergence, subnotebooks were also distinguished from netbooks and ultra-mobile PCs, based on both size and market position. Classic subnotebooks were smaller than full sized laptops but larger than handheld computers. They were distinguished by smaller screens and bodies and lighter weights relative to contemporaneous laptops. The savings in size and weight were often achieved p ...
