Genoa Systems

Genoa Systems is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Genoa Systems rather than just read about it. In short: Genoa Systems Corporation, later Genoa Electronics Corporation, was an American computer multimedia peripheral vendor based in San Jose, California, and active from 1984 to 2002. The company was once a prolific and well-known manufacturer of video cards and chipsets.

Key takeaways

  • Genoa Systems belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Genoa Systems to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Genoa Systems from memory before moving on to harder problems.

Reference excerpt

Genoa Systems Corporation, later Genoa Electronics Corporation, was an American computer multimedia peripheral vendor based in San Jose, California, and active from 1984 to 2002. The company was once a prolific and well-known manufacturer of video cards and chipsets. The company also dabbled in modems, tape drives, sound cards, and other peripheral expansion cards. Genoa was a founding member of the Video Electronics Standards Association (VESA) and was instrumental in the development of Super VGA.

History

Foundation (1984–1987)

Genoa Systems was founded in 1984 in San Jose, California, as a subsidiary of the Ching Fong Investment Company, a Taiwanese holding company headquartered in the United States in San Francisco. Genoa Systems was one of several high-tech companies that Ching Fong had founded in the early 1980s. Genoa's principal co-founder was Taiwan-born Frank C. Lin, who previously worked for Olivetti as a senior manager. He was named Genoa's president and served that role until 1987, when he left to found Trident Microsystems, a fabless semiconductor company, in Mountain View, California. Genoa's first video-related product was the Spectrum Graphics Card in fall 1985. Released for the IBM Personal Computer and compatibles, the Spectrum combined multiple graphics adapter standards that were previously spread across multiple cards—CGA, MDA, Hercules, and Plantronics. Genoa released an updated variant of the Spectrum only a few months later in late 1985, the Spectrum Plus, which integrated many of the discrete chips necessary to drive the disparate graphics modes into one VLSI chip. In early 1986, they released the Spectra EGA, which InfoWorld evaluated as closely mimicking IBM's original Enhanced Graphics Adapter card—down to emulating its bugs when running certain software such as Lotus 1-2-3. In late 1986, the company released the Genoa SuperEGA board featuring their own bespoke chipset, which extended IBM's EGA standard by adding a resolution mode capable of displaying graphics at 640 by 480 pixels. It was also backwards compatible with CGA, MDA, and Hercules. The SuperEGA chipset was the first such product on the market, with Genoa beating out their competitors Chips and Technologies and Video Seven. As well as selling their own board featuring the chipset, Genoa sold the chipset to other manufacturers, in volume orders. In 1987, they extended the EGA standard further with the SuperEGA HiRes, which added a resolution mode capable of displaying 800-by-600-pixel graphics. Genoa were also active in other areas of the PC marketplace, including internal and external modems (under the name NovaCom) and external backup tape drives (under the name Galaxy). By 1986, the company had over 1,000 dealers across the globe and posted annual sales of roughly $18 million.

Market success and VGA innovations (1987–1998)

After EGA was rendered obsolete by the release of IBM's Video Graphics Array (VGA) technology in 1987, Genoa pioneered a number of extensions to the VGA standard. These extensions were standardized and collectively known as Super VGA after the Video Electronics Standards Association (VESA) consortium was formed in November 1988. Genoa likely coined the term Super VGA with the release of the SuperVGA and SuperVGA HighRes boards in late 1987. Genoa was a founding member of VESA in 1988, along with Video Seven, STB Systems, Paradise Systems, Tecmar, and NEC. In January 1989, Genoa partnered with Western Digital (the parent company of Paradise Systems) and Sigma Designs to invest in Vitelic, a San Jose startup, who were planning on raising a DRAM fabrication plant in San Francisco. In fall 1989, Genoa introduced a family of Super VGA graphics cards that were the first to offer 70 MHz refresh rates in VGA modes. These cards were compatible only with the professional multisync CRT monitors just coming on the market at the time but eliminated the perceived flicker that CRTs displaying 60 MHz signals tended to exhibit. The family of cards comprised the 8-bit ISA-based 6100 (with 512 KB of VRAM); the 16-bit ISA-based 6300 (with 256 KB of VRAM) and 6400 (with 512 KB of VRAM); and the 16-bit MCA-based 6600 (with 512 KB of VRAM). The company began dabbling in sound cards for PCs starting in 1994, with the release of the AudioBlitz Classic. Models in the AudioBlitz range were mostly based on Yamaha OPL3 and OPL4 sound chips.

Decline (1998–2002) In the last few years of its existence, Genoa moved its headquarters to Fremont, California, changed its name to Genoa Electronics Corporation, and focused on the development of an embedded computer marketed as an information and Internet appliance. Eventually realized as the Genoa Embedded Information Appliance (GEIA), it was marketed for use in kiosks in financial institutions and insurance companies, as thin clients for schools, and as set-top boxes for home use. The GEIA was a commercial flop, and by 2002, Genoa had folded completely.

Worked examples

Example 1 — a first encounter with Genoa Systems

Start with the simplest possible case. Write down what Genoa Systems claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Genoa Systems before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Genoa Systems ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Genoa Systems

In research
Genoa Systems appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Genoa Systems in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Genoa Systems is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1984 establishments in California, 2002 disestablishments in California, American companies disestablished in 2002, so understanding it makes those chapters shorter.
In everyday life
Look for Genoa Systems outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
