TextureJet slider is one of those, but I could not get any relevant difference by changing its value. By using this site, you agree to the Terms of Use and Privacy Policy. By the end of Laguna3D was ready for mass production, but the specifications were nothing like M2. It may also be the reason for no OpenGL games support.

A year later came second joint fabrication venture with Lucent named Cirent. That is standard rasterizer of lotic time, sitting between FIFOs and feeds from own 16 kB of registers.

So there are different opinions whether the company was mismanaged or logicc of its own success. In other projects Wikimedia Commons. Even if execution units are designed to process multiple operations in single pass, their inputs cannot be fed fast enough.

Incoming in 32 bit mode, no sign of dithering, but broken lens flares still ruin the show. All the development process required was a systems engineer who could icrrus and arrange the chips to handle whatever function the product should perform.

The patented use of tiled memory used by the GDx chips is still used by firrus all graphics processors today. The goal of Cirrus was to create a high-end card by integrating 3DO’s technology into own architecture.


Cirrus Logic Laguna3D review

Laguna3D has pins for second channel already reserved, to maintain the same board layout with future planned products using two channels to double the memory bandwidth. Taking price into account it performs quite well in old games even with small amount of local memory.

French joined Cirrus Logic, Inc. 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. Pixels are tested cirruz masks and depth comparison performed with help by cache, before lighting and blending is processed.

Laguna3D turned into problem child, which was sold mostly for discount prices. Laguna3D PCI merely once calculates interpolated color between pixels and uses that, effectively doubling their amount. No other 3d graphics provider got such an endorsement from mighty Logiv. Lack of own fabrication seemed to stand in a way of further expansion and Cirrus. Up to 4 way interleaving is possible. Then there are games partially giving up on texturing, likely because of failure in lightmap phase, those are using or originating from Quake engine, like Half Life loogic Thief.

Anyway, focus then moved onto storage, audio chips and data acquisition technology used for communication and industrial applications. Fabrication partnerships with both IBM and Lucent were ended.

3-Channel, Single Phase Power/Energy IC

Promised fogging is failing across game suit. The texture manager is supported with 1 kilobyte texture cache and on-chip address translation table that tracks, via dynamic random accessing, all the memory locations of textures being used. Setting the lowest value gives Laguna a speed increase, but perspectives are getting really fuzzy. For more screenshots see the Laguna3D gallery.


Experience First big complaint about image quality is broken texture perspective correction. Both 2 and 4 MB variants are common.

Cirrus Logic

By the end of Laguna3D was ready for mass production, but the specifications were nothing like M2. Inside the chips loic other obvious improvement is fixed bilinear filter, which I will get to later.

The AGP version would then be also a bug fixing effort. If Laguna3D could draw full featured 3d pixel in single cycle as Cirrus claimed, this should not be a contest, but as you can see it rarely happens.

In April Cirrus has licensed the 3D portion of 3DO’s M2 technology, a bit graphics acceleration built for new console. Cirrus got a jump start into 3D technology by acquiring patents and several engineers of Austek, company which has just developed A OpenGL accelerator. But some games don’t like textures outside of local memory, like Loguc Racing shows by switching to very small mipmaps, and Incoming drops texturing completely.

Cirrus Logic went public in and cireus growth through acquisitions among which were Pixel Semiconductor and Acumos.
