CIRRUS LOGIC GD5480 DRIVER

Cirrus Logic went public in and accelerated growth through acquisitions among which were Pixel Semiconductor and Acumos. New millennium brought a growing demand for consumer electronics products based on digital audio and video technologies, which was a good wind for Cirrus and it carries them till today. Creative once again bought rights for early release, and more interestingly, they announced their Laguna3D will be compatible with CGL. Soon after joining the company, through an acquisition strategy Mr. Anyway, focus then moved onto storage, audio chips and data acquisition technology used for communication and industrial applications.

Creative once again bought rights for early release, and more interestingly, they announced their Laguna3D will be compatible with CGL.

Michael Hackworth was named president and chief executive officer in Januaryand served as CEO until February Up to 8 MB of local memory are supported and Techworks planned to release 6 and 8 MB cards, but I don’t think that ever xirrus.

There are more interesting settings to play with in Laguna registry, though they seem mostly applicable only for AGP version of Laguna3D. Lack of own fabrication seemed to stand in cirrrus way of further expansion and Cirrus.

Cirrus Logic

In the early s, Cirrus Logic became a supplier of PC graphics chips, audio converters and chips for magnetic storage products. Flexible yet fabless way was to at least buy long term foundry capacity. Everything seemed to be in place, and Cirrus promised shipping of first 3D gd480 by the end of TextureJet slider is one of those, but I could not get any relevant difference by changing its value.

Overall Laguna3D claimed performance of more than 50 million “perspective-corrected” textured pixels per second. Business Wire archived at the Free Library.

Laguna3D turned into problem child, which was sold mostly for discount prices. It may also be the reason for no OpenGL games support. Soon after joining the company, through an acquisition strategy Mr. It was in similar market segment, and suffered from it’s own blending and perspective correction problems.

Retrieved from ” https: It joined the Nasdaq market listing in symbol: Retrieved 20 August Cirrus got a jump start into 3D technology by acquiring patents and several engineers citrus Austek, company which has just developed A OpenGL accelerator.

By the end of Laguna3D was ready for mass production, but the specifications were nothing like M2. Mondello development took a back seat to the GD which was near completion and proved to be a much faster design with the use of Rambus.

From Wikipedia, the free encyclopedia. I don’t know why exactly Mondello wasn’t finished, but price would probably be quite high and therefore aimed at the professional market. Smoke in Carmageddon is not bilineary filtered and car shadow flickers, shadows in Expendable are drawn on top, status bar in Formula 1 is broken. Cirrus was especially fond of it’s texturing engine, calling it TextureJet architecture. M2, on paper at least, was no joke with half million polygons triangle setup and million pixels per second fillrate.

All the development process required was a systems engineer who could program and arrange the chips to handle whatever function the product should perform. French joined Cirrus Logic, Inc. The AGP version would then be also a bug fixing effort. Initial promotion price of hundred bucks should be a sign that Laguna3D is not so hot performer.

The patented use of tiled memory used by the GDx chips is still used by nearly all graphics processors today. Clock of Rambus controller is half of data rate, which means own domain ticking at frequency of MHz. For example, the Cirrus GD supported hardware acceleration for both 8-bit color and bit color.
