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
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 ...

IBM 486SLC
The 386SLC is an Intel-licensed version of the 386SX (32-bit internal, 16-bit external, 24-bit memory addressing), developed and manufactured by IBM in 1991. It included power-management capabilities and an 8KB internal CPU cache, which enabled it to yield comparable performance to 386DX processors of the same clock speed, which were considerably more expensive. Known inside IBM as ''"Super Little Chip"'' for its initials, it was used in the IBM PS/2 35, 40 and 56 Series and in the IBM PS/ValuePoint 325T, but never gained much market share. This was mainly due to an agreement with Intel, in which IBM was not allowed to sell their CPUs if they were not part of a system or upgrade board. It was also marketed as an optional upgrade for 8086-equipped IBM PS/2 25 Series computers. Design and Technology Built with complementary metal oxide semiconductor ( CMOS) technology, the IBM 386SLC had a 161-square millimeter die. It was available with clock speeds of 16, 20, and 25 MHz.

Fort Worth Star-Telegram
The ''Fort Worth Star-Telegram'' is an American daily newspaper serving Fort Worth and Tarrant County, the western half of the North Texas area known as the Metroplex. It is owned by The McClatchy Company. History In May 1905, Amon G. Carter accepted a job as an advertising space salesman for the new newspaper The ''Fort Worth Star''. She printed her first newspaper on February 1, 1906, with Carter as the advertising manager, and Louis J. Wortham as its first editor. The Financier and President of the Fort Worth Star was Colonel Paul Waples, head of the Waples Platter Company and instrumental in nearly all of early Fort Worth institutions. The ''Star'' lost money, and was in danger of going bankrupt when Carter, and Wortham went to Waples. He cut a check for the additional funds and purchased his newspaper's main competition, the ''Fort Worth Telegram''. In November 1908, the ''Star'' purchased the ''Telegram'' for $100,000, and the two newspapers combined on January 1, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quad Flat Package
A quad flat package (QFP) is a surface-mounted integrated circuit package with "gull wing" leads extending from each of the four sides. Socketing such packages is rare and through-hole mounting is not possible. Versions ranging from 32 to 304 pins with a pitch ranging from 0.4 to 1.0 mm are common. Other special variants include low-profile QFP (LQFP) and thin QFP (TQFP). The first QFPs were introduced in Japan in 1977 in order to provide more pins on a small package to allow a greater number of digits on electronic calculators. It soon spread to other consumer electronics in that country. The QPF only became common in Europe and United States during the early nineties. It is often mixed with hole mounted, and sometimes socketed, components on the same printed circuit board (PCB). A package related to QFP is plastic leaded chip carrier (PLCC) which is similar but has pins with larger pitch, 1.27 mm (or 1/20 inch), curved up underneath a thicker body to simpli ...

486DLC
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 ...

Laptop
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a Clamshell design, clamshell form factor (design), form factor with a flat-panel computer screen, screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is in the lower part, under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for PC game, playing games, Content creation, content creating, web browser, web browsing, for personal multimedia, and for general P ...

Motherboard
A motherboard, also called a mainboard, a system board, a logic board, and informally a mobo (see #Nomenclature, "Nomenclature" section), 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 computer memory, memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the CPU, the chipset's input/output and Memory controller, memory controllers, interface (computing), interface connectors, and other components integrated for general use. Nomenclature ''Oxford English Dictionary'' traces the origin of the word ''motherboard'' to 1965, its earliest-found attestation occurring in the magazine ''Electronics (magazine), Electronics''. The term alludes to its importance and size compared to the components attached to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

L1 Cache
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I- or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM. Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (MMU) whic ...
