Cyrix
Cyrix Corporation was a microprocessor developer that was founded in 1988 in Richardson, Texas, as a specialist supplier of floating point units for 286 and 386 microprocessors. The company was founded by Tom Brightman and Jerry Rogers. Terry Rogers was also serving as the company Chief Executive Officer and president up until December 9, 1996, when he stepped down from this role, but remained on the Board of Directors. In 1992, Cyrix introduced its own i386 compatible processors, the 486SLC and 486DLC. These had higher performance than the Intel parts, but a lower price. They were primarily marketed to users looking to upgrade existing machines. Their release sparked a lengthy series of lawsuits with Intel while their foundry partner IBM was releasing the same designs under their own branding. The combination of these events led Cyrix to begin losing money, and the company merged with National Semiconductor on 11 November 1997. National released Cyrix's latest designs ...

Cyrix Cx486SLC
The Cyrix Cx486SLC is a x86 microprocessor that was developed by Cyrix. It was one of Cyrix's first CPU offerings, released after years of selling math coprocessors that competed with Intel's units and offered better performance at a comparable or lower price. It was announced in March of 1992, and released 2 months later in May, with a price of $119. It was priced competitively against the Intel 486SX, causing Intel to lower the price of their chip from $286 to $119 in just days. Specifications The 486SLC is based on the i386SX bus, and was intended as an entry-level chip to compete with the Intel 386SX and 486SX. SGS-Thomson and Texas Instruments manufactured the 486SLC for Cyrix. Texas Instruments also sold it under its own name as TX486SLC. Later, Texas Instruments also released their own version of the chip, the TI486SXLC which featured 8KB internal cache vs 1KB in the original Cyrix design. These chips went under the name Potomac, and Cyrix would receive full royaltie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyrix Cx486DLC
The Cyrix Cx486DLC is an x86 desktop microprocessor developed by Cyrix. It was Cyrix's second CPU offering, released years after selling math coprocessors that competed with Intel's units and offered better performance at a comparable or lower price. It was released in June of 1992, with a price of $119 for computer manufacturers. Specifications The 486DLC is a 486 desktop CPU from Cyrix, intended to compete with the Intel 486SX and DX. Texas Instruments, who manufactured the 486DLC for Cyrix, later released its own version of the chip, the TI486SXL, with 8 KB internal cache vs 1 KB of the original Cyrix design. The similarly named IBM 486DLC, 486DLC2, 486DLC3 (aka Blue Lightning) are often confused with the Cyrix chips, but are not related and are instead based on Intel's i486 design. Like the later and more famous Cyrix Cx5x86, it is a hybrid CPU, incorporating features of a new CPU (the Intel 80486) while plugging into its predecessor's (386DX) PGA132 socket. It runs ...

MediaGX
The MediaGX CPU is an x86-compatible processor that was designed by Cyrix and manufactured by National Semiconductor following the two companies' merger. It was introduced in 1997. The core is based on the integration of the Cyrix Cx5x86 CPU core with hardware to process video and audio output (XpressRAM, XpressGRAPHICS, XpressAUDIO). Following the buyout of Cyrix by National Semiconductor and the sale of the Cyrix name and trademarks to VIA Technologies, the core was developed by National Semiconductor into the Geode line of processors, which was subsequently sold to Advanced Micro Devices. Whether this processor belongs in the fourth or fifth generation of x86 processors can be considered a matter of debate as the processor was based on the 5x86 (a scaled down version of the Cyrix 6x86). While the 5x86 was intended to compete with the Intel Pentium line, the 5th generation x86, it was designed to interface with a 4th generation ( 80486) motherboard and had only the 486's ins ...

Geode (processor)
Geode is a series of x86-compatible system-on-a-chip (SoC) microprocessors and I/O companions produced by AMD that was targeted at the Embedded system, embedded computing market. The series was originally launched by National Semiconductor as the Geode family in 1999. The original Geode processor core itself is derived from the Cyrix MediaGX platform, which was acquired in National's merger with Cyrix in 1997. AMD bought the Geode business from National in August 2003 to augment its existing line of embedded x86 processor products. Before acquiring Geode, AMD marketed the AMD Élan, a family of 32-Bit embedded SoCs based on their own Am386, Am486 and Am586 microprocessors. All of these products have been backed with a long-term supply guarantee to meet the needs of embedded processors. However, after acquiring Geode, the product was suddenly discontinued. AMD expanded the Geode series to two classes of processor: the MediaGX-derived Geode GX and LX, and the modern Athlon-derived ...

I386
The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture. Pre-production samples of the 386 were released to select developers in 1985, while mass production commenced in 1986. The 386 was the central processing unit (CPU) of many workstations and high-end personal computers of the time. The 386 began to fall out of public use starting with the release of the i486 processor in 1989, while in embedded systems the 386 remained in widespread use until Intel finally discontinued it in 2007. Compared to its predecessor the Intel 80286 ("286"), the 80386 added a three-stage instruction pipeline which it brings up to total of 6-stage instruction pipeline, extended the architecture from 16-bits to 32-bits, and added an on-chip memory management unit. This paging translation unit made it muc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Floating Point Unit
A floating-point unit (FPU), numeric processing unit (NPU), colloquially math coprocessor, is a part of a computer system specially designed to carry out operations on floating-point numbers. Typical operations are addition, subtraction, multiplication, division, and square root. Modern designs generally include a fused multiply-add instruction, which was found to be very common in real-world code. Some FPUs can also perform various transcendental functions such as exponential or trigonometric calculations, but the accuracy can be low, so some systems prefer to compute these functions in software. Floating-point operations were originally handled in software in early computers. Over time, manufacturers began to provide standardized floating-point libraries as part of their software collections. Some machines, those dedicated to scientific processing, would include specialized hardware to perform some of these tasks with much greater speed. The introduction of microcode in the ...
