English, spanish, japanese and chinese language = OK Au sujet de cette marque / about DEC, (source wikipedia): Digital Equipment Corporation (DEC /dɛk/), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until forced to resign in 1992, after the company had gone into precipitous decline. Although the company produced many different product lines over their history, they are best known for their work in the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis of all time. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially with the introduction of RISC-based workstation machines, the performance niche of the minicomputer was rapidly eroded. By the early 1990s, the company was in turmoil as their mini sales collapsed and their attempts to address this by entering the high-end market with machines like the VAX 9000 were market failures. After several attempts to enter the workstation and file server market, the DEC Alpha product line began to make successful inroads in the mid-1990s, but was too late to save the company. DEC was acquired in June 1998 by Compaq in what was at that time the largest merger in the history of the computer industry. During the purchase, some parts of DEC were sold to other companies; the compiler business and the Hudson, Massachusetts facility, were sold to Intel. At the time, Compaq was focused on the enterprise market and had recently purchased several other large vendors. DEC was a major player overseas where Compaq had less presence. However, Compaq had little idea what to do with its acquisitions, and soon found itself in financial difficulty of its own. The company subsequently merged with Hewlett-Packard (HP) in May 2002. La société a été fondée en 1957 par Ken Olsen, un ingénieur du Massachusetts qui avait travaillé sur le projet TX-2 au laboratoire Lincoln du Massachusetts Institute of Technology (MIT). Le TX-2 était un ordinateur basé sur des transistors. Lorsque ce projet rencontra des difficultés, Olsen le quitta pour fonder DEC avec Harlan Anderson (en), un collègue du MIT. À cette époque les investisseurs n'étaient pas favorables aux sociétés informatiques. Ils commencèrent donc par construire des petits modules numériques (correspondant aux composants du TX-2) pouvant être combinés pour être utilisés dans un laboratoire. En 1961 la société était bénéficiaire et commença la construction de son premier ordinateur: le PDP-1. Durant les années 1960 DEC produit une série d'ordinateurs ayant un meilleur rapport prix/performances que ceux d'IBM, généralement basés sur des mots de 18 bits. Le succès arriva en 1964 avec le PDP-8. Il s'agissait d'un ordinateur 12 bits vendu environ 16 000 $. Le PDP-8 était assez petit pour tenir sur un chariot. Il était assez simple d'usage pour de nombreuses applications et conquit de nombreux marchés de niche, laboratoires, chemins de fer et applications industrielles. Le PDP-8 est aujourd'hui considéré comme le premier mini-ordinateur. Le dernier ordinateur marquant de la série PDP est le PDP-11. Il utilisait des mots de 16 bits pour supporter les caractères ASCII devenus standards. Il avait 64 kilooctets de RAM. Il est notamment connu pour avoir été l'ordinateur sur lequel UNIX et le langage C ont été développés. En 1976, DEC conçut une nouvelle architecture 32 bits et joue un rôle capital dans le lancement d'une course aux machines moins coûteuses, plus maniables et plus puissantes, face au monopole IBM. Elle fut introduite en 1978 par le VAX 11/780 et s'empara rapidement du marché des mini-ordinateurs. Les VAX pouvaient être utilisés avec le système d'exploitation UNIX ou VMS de DEC. Le succès commercial de DEC culmina vers la fin des années 1980. C'était le second plus grand constructeur d'ordinateurs et comptait 100 000 employés. À ce moment DEC proposait de nombreux produits propriétaires comme le réseau DECnet. Comme ces produits n'étaient conçus pour fonctionner qu'avec des produits DEC, les consommateurs se tournèrent vers des produits plus standards. Au même moment les performances des stations de travail RISC rejoignaient celles des VAX. Malheureusement Ken Olsen ne crut pas en l'avenir de l'informatique individuelle et Digital manqua le virage du PC.

The PA-7300LC The First "System on a Chip" Presented at Microprocessor Forum on 10/16/95 by Tom Meyer The PA-7300LC is a new processor design, which features a high level of integration of system functions. HP's PA-RISC processor family currently features two "streams" of CPU development. Each is optimized to meet the needs of different classes of computer systems. The high-end stream, which includes the PA-7200 and PA-8000 chips, is optimized for very high performance, highly expandable power desktops and servers. Several years ago it was determined that HP could best meet the needs of higher volume, more cost sensitive products by developing a different set of CPUs tuned to the special requirements of these systems. This processor line began with the PA-7100LC, which first began shipping in January of 1994, and continues with the new design described in this paper. We refer to this as our "low end" but it is also a "no compromise" stream, since we consider cost, performance, power, and other design objectives to all be equally high priority. Meeting the design objectives by finding the right balance between these factors is the main challenge in this area of microprocessor design. Design Objectives The design objectives of the PA-7300LC chip are nearly identical to those of its predecessor, which has proven to be a successful volume work-horse processor. Design improvements and a more advanced VLSI technology have allowed the designers to achieve roughly twice the performance of the 100MHz PA-7100LC without compromising cost or any of the other objectives. Like previous PA-RISC chips, the team evaluated the cost of design tradeoffs using a holistic approach which emphasizes total system cost, rather than just trying to design a cheap microprocessor without regard to the rest of the system. In defining the PA-7300LC HP's design team carefully considered the requirements of realistic system applications and tuned the design to meet those needs rather than just optimizing for microprocessor-level benchmarks. As a result, a large part of the design effort focused on minimizing the number of system components, reducing test and diagnostic costs, and getting the right level of functional partitioning. System designers and manufacturing engineers were consulted throughout the design. As you will see, many chip level features have been included to address these objectives. PA-7300LC Overview This design features a superscalar processor core that was highly leveraged from the PA-7100LC core. Enhancements include a large on-chip primary cache, an integrated DRAM and L2 cache controller, and an improved I/O bus controller. The chip uses established technologies including HP's half micron CMOS process and a low-cost ceramic pin-grid array package. The preliminary performance projections you see here assume 1 Mbyte of secondary cache and 60ns fast-page-mode DRAMs, but the chip can be configured with higher performance memory components. We believe that this processor will do very well on memory intensive programs as shown by the SPEC95 and OLTP estimates. This is because of the highly optimized memory hierarchy I will describe in a moment. PA-7300LC Chip Layout The RISC processor core, consisting of the integer units, floating-point unit, and instruction decode logic occupy the right side of the die. The center blocks contain the virtual memory translation lookaside buffer (TLB) and Memory and I/O controller or MIOC. The large, denser-looking blocks are the instruction and data caches. Nearly 8 million of the 9.2 million transistors are contained in these two blocks. As you can see, a large amount of chip real estate is devoted to embedded SRAM for the primary caches. It's been said that future microprocessors will look like large memory chips with a small microprocessor block in the corner. The 7300LC has really headed in that direction with this chip since the cache arrays occupy 40% of the chip area. As a si
