That is standard rasterizer of the time, sitting between FIFOs and feeds from own 16 kB of registers. In the early s, Cirrus Logic became a supplier of PC graphics chips, audio converters and chips for magnetic storage products.

When Intel announced they were entering the 3D market with the i Cirrus Logic exited the market, which at the time for Cirrus Logic was worth million dollars annually. Incoming in 32 bit mode, no sign of dithering, but broken lens flares still ruin the show. Our processors would appreciate more something like triangle setup, but at least there is something unique inside Laguna3D.

That was one big nail into Laguna3D’s coffin, because with advancing time game developers were using it more and more. Cirrus got a jump start into cirru technology by acquiring patents and several engineers of Austek, company which has just developed A OpenGL accelerator.

Even if execution units are designed to process multiple operations in single pass, their inputs cannot be fed fast enough. Cirrus took td5480 of PC boom and finally succeeded with own hard drive controller, first to be mounted inside the drive mechanism.


Cirrus Logic Laguna3D review

There are more interesting settings to play with in Laguna registry, though they seem mostly applicable only for AGP version of Laguna3D. It is nice when accelerator uses higher internal precision, but dither pattern employed by Laguna is far from accurate and several overlapping layers of transparent textures can deliver awful almost stipple-like pattern. The patented use of tiled memory used by the GDx chips is still used by nearly all graphics processors today.

World texturing does not work in those, promise of single lighting pass from spec sheets is really only for basic techniques. Unreal just skips lightmaps alone and Laguna is useless for other effects as well.

The raw processing power of the GDx was nearly 2. 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 happened. The CL-GD chip ought to be disappoing, because bilinear texture filter is one of the cheapest possible implemntation. InfoWorld Media Group, Inc.

Cirrus Logic CL-GD

Cirrus was especially fond of it’s texturing engine, calling it TextureJet architecture. Then there is rather heavy dithering to 16 bit colors. For example, the Cirrus GD supported hardware acceleration for both 8-bit color and bit color.

Emulated Cirrus Logic graphic cards are used in emulators. Suhas Patil founded the company as “Patil Systems, Inc. The company announced in April that it had completed moving its headquarters to Austin, Texas.


InHackworth stepped down and Cirrus went through continues changes. By the end of Laguna3D was ready for mass production, but the specifications were nothing like M2. Lack of own fabrication seemed to stand in a way of further expansion and Cirrus. Retrieved January 14, All basic blending modes are supported except one- multiplicative blending.

The Industry’s Foundation for High Performance Graphics

Retrieved from ” https: This page was last edited on 30 Septemberat Battlezone and Interstate 76 demo reject the card outright. All the development process required was a systems engineer who could program and arrange the chips to handle whatever function the product should perform.

In between those Cirrus is making a point for AGP. TextureJet slider is one of those, but I could not get any relevant difference by changing its value. It joined the Nasdaq ggd5480 listing in symbol: After three years of struggle Patil contacted Hackworth, back then in Signetics.
