VIA Eden
VIA Eden is a name of a variant of VIA's C3/ C7 x86 processors, designed to be used in embedded devices. They have smaller package sizes, lower power consumption, and somewhat lower computing performance than their C equivalents, due to reduced clock rates. They are often used in EPIA mini-ITX, nano-ITX, and Pico-ITX motherboards. In addition to x86 instruction decoding, the processors have a second undocumented Alternate Instruction Set. The Eden is available in four main versions: * Eden ESP: Samuel 2 and Nehemiah cores (300 MHz-1.0 GHz) - EBGA 35mm×35mm package, 66/100/133 MHz FSB * Eden-N: Nehemiah core (533 MHz-1.0 GHz) - NanoBGA 15mm×15mm package, 133 MHz FSB * Eden: Esther core (400 MHz-1.2 GHz) - NanoBGA2 21mm×21mm package, 400 MT/s FSB * Eden ULV: Esther core (500 MHz-1.5 GHz) - NanoBGA2 21mm×21mm package, 400 MT/s FSB The Eden ULV 500 MHz was the first variant to achieve a TDP of 1W .http://www.viatech.com/en/ ...

CPU VIA EDEN ESP N8000
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other compo ...

VIA Technologies
VIA Technologies Inc. (), is a Taiwanese manufacturer of integrated circuits, mainly motherboard chipsets, CPUs, and memory. It was the world's largest independent manufacturer of motherboard chipsets. As a fabless semiconductor company, VIA conducts research and development of its chipsets in-house, then subcontracts the actual (silicon) manufacturing to third-party merchant foundries such as TSMC. History The company was founded in 1987, in Fremont, California, USA by Cher Wang. In 1992, it was decided to move the headquarters to Taipei, Taiwan in order to establish closer partnerships with the substantial and growing IT manufacturing base in Taiwan and neighbouring China. In 1999, VIA acquired most of Cyrix, then a division of National Semiconductor. That same year, VIA acquired Centaur Technology from Integrated Device Technology, marking its entry into the x86 microprocessor market. VIA is the maker of the VIA C3, VIA C7 & VIA Nano processors, and the EPIA platform. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VIA C3
The VIA C3 is a family of x86 central processing units for personal computers designed by Centaur Technology and sold by VIA Technologies. The different CPU cores are built following the design methodology of Centaur Technology. In addition to x86 instructions, VIA C3 CPUs contain an undocumented Alternate Instruction Set allowing lower-level access to the CPU and in some cases privilege escalation. Cores Samuel 2 and Ezra cores VIA Cyrix III was renamed VIA C3 with the switch to the advanced "Samuel 2" (C5B) core. The addition of an on-die L2 cache improved performance somewhat. As it was not built upon Cyrix technology at all, the new name was just a logical step. To improve power consumption and reduce manufacturing costs, Samuel 2 was produced with 150 nm process technology. The VIA C3 processor continued an emphasis on minimizing power consumption with the next die shrink to a mixed 130/150 nm process. "Ezra" (C5C) and "Ezra-T" (C5N) were only new revisions o ...

VIA C7
The VIA C7 is an x86 central processing unit designed by Centaur Technology and sold by VIA Technologies. Product history The C7 delivers a number of improvements to the older VIA C3 cores but is nearly identical to the latest VIA C3 Nehemiah core. The C7 was officially launched in May 2005, although according to market reports, full volume production was not in place at that date. In May 2006 Intel's cross-licensing agreement with VIA expired and was not renewed, which was the reason for the forced termination of C3 shipments on March 31, 2006, as VIA lost rights to the socket 370. The C7 appears still to be found in the marketplace, for example, on the bargain-priced Everex TC2502, sold by Walmart with a Linux distribution preinstalled and on the HP Mini-Note. A 1 GHz C7 processor with 128kB of cache memory is used in VIA's own PX10000G motherboard which is based on the proprietary Pico-ITX form factor. The chip is cooled by a large heatsink that covers most of the boa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mini-ITX
Mini-ITX is a motherboard form-factor, developed by VIA Technologies in 2001. They are commonly used in small-configured computer systems. Originally, they were a niche product, designed for fan-less cooling with a low power consumption architecture, which made them useful for home theater PC systems, where fan noise can detract from the cinema experience. The four mounting holes in a Mini-ITX board line up with four of the holes in ATX-specification motherboards, and the locations of the backplate and expansion slot are the same (though one of the holes used was optional in earlier versions of the ATX spec). Mini-ITX boards can therefore often be used in cases designed for ATX, micro-ATX and other ATX variants if desired. The design provides one expansion slot. Earlier motherboards conventionally have a standard 33 MHz 5V 32-bit PCI slot. Many older case designs use riser cards and some even have two-slot riser cards, although the two-slot riser cards are not compatible ...

Nano-ITX
Nano-ITX is a computer motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005. Nano-ITX boards measure , and are fully integrated, very low power consumption motherboards with many uses, but targeted at smart digital entertainment devices such as Digital video recorder, DVRs, set-top boxes, Home theater PC, media centers, car PCs, and thin devices. Nano-ITX motherboards have slots for SO-DIMM. There are four Nano-ITX motherboard product lines so far, VIA's EPIA N, EPIA NL, EPIA NX, and the VIA EPIA NR. These boards are available from a wide variety of manufacturers supporting numerous different CPU platforms. Udoo has now released at least 1 nano-ITX board: the Udoo Bolt.

Pico-ITX
In computer design, Pico-ITX is a PC motherboard form factor announced by VIA Technologies in January 2007 and demonstrated later the same year at CeBIT. The formfactor was transferred over to SFF-SIG in 2008. The Pico-ITX form factor specifications call for the board to be , which is half the area of Nano-ITX. EPIA PX PX10000G The first motherboard produced in this form factor is called EPIA PX10000G. It is and 10 layers deep. The operating temperature range is from 0°C to about 50°C. The operating humidity level (relative and non-condensing) can be from 0% to about 95%. It uses a 1 GHz VIA C7-M processor, a VIA VX700 chip set, and is RoHS compliant. It has onboard VGA video, VIA VT6106S 10/100 8P8C Ethernet, UDMA 33/66/100/133 44-pin ATA (1x), and SATA (1x) I/O. DVI and LVDS video-out, USB 2.0, COM, PS/2 Mouse & Keyboard, and HD 5.1 channel audio (supplied by a VIA VT1708A chip) are supported through the usage of I/O pin headers and add-on modules/daughter c ...

Motherboard
A motherboard (also called mainboard, main circuit board, mb, mboard, backplane board, base board, system board, logic board (only in Apple computers) or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general use. ''Motherboard'' means specifically a PCB with expansion capabilities. As the name suggests, this board is often referred to as the "mother" of all components attached to it, which often include peripherals, interface cards, and daughterboards: sound cards, video cards, network cards, host bus adapters, TV t ...

Alternate Instruction Set
The Alternate Instruction Set (AIS) is a second 32-bit instruction set architecture found in some x86 CPUs made by VIA Technologies. On these VIA C3 processors, the second hidden processor mode is accessed by executing the x86 instruction ALTINST (). If AIS mode has been enabled, the processor will perform a JMP EAX and begin executing AIS instructions at the address of the EAX register. Using AIS allows native access to the Centaur Technology-designed RISC core inside the processor. Instruction format The manufacturer describes the Alternate Instruction Set as "an extended set of integer, MMX, floating-point, and 3DNow! instructions along with additional registers and some more powerful instruction forms". Every AIS instruction is prefixed with the 3-byte sequence 0x8D8400 followed by the 32-bit instruction; this prefix form for the AIS instructions makes them appear to be x86 Load Effective Address (LEA) instructions. In 2018 researcher Christoper Domas reported that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Design Power
The thermal design power (TDP), sometimes called thermal design point, is the maximum amount of heat generated by a computer chip or component (often a CPU, GPU or system on a chip) that the cooling system in a computer is designed to dissipate under any workload. Some sources state that the peak power rating for a microprocessor is usually 1.5 times the TDP rating. Intel has introduced a new metric called ''scenario design power'' (SDP) for some Ivy Bridge Y-series processors. Calculation The ''average CPU power'' (ACP) is the power consumption of central processing units, especially server processors, under "average" daily usage as defined by Advanced Micro Devices (AMD) for use in its line of processors based on the K10 microarchitecture ( Opteron 8300 and 2300 series processors). Intel's thermal design power (TDP), used for Pentium and Core 2 processors, measures the energy consumption under high workload; it is numerically somewhat higher than the "average" ACP rat ...
