Appl. No.:

10/648496

Inventors:

Fred Liao - San Jose CA, US
Michael Hong - Cupertino CA, US

Assignee:

Via Technologies, Inc. - Taipei

International Classification:

G06T 17/00

US Classification:

Abstract:

Z buffer traffic experienced during graphics processing is reduced by using a compression mechanism to reduce the amount of information stored in the z buffer. The compression mechanism may be a delta-based z compression mechanism, which stores deltas in the z buffer rather than actual z values. These deltas may be used at a later time to compute the z values. By storing deltas instead of actual z values, the compression mechanism makes it possible to store significantly less information in the z buffer. By reducing the amount of information stored in the z buffer, less information will be read from and written to the z buffer, which in turn, reduces z buffer traffic. To further reduce z buffer traffic, selected deltas may be stored not in the z buffer but rather in a storage local to a graphics processing mechanism (GPM). Storing selected deltas in local storage obviates the need to read from or write to the z buffer for those deltas. As a result, z buffer traffic is even further reduced.

Abstract:

The present invention is generally directed to a multi-pass rendering system and method. In one embodiment, in first pass of a graphics primitive data through a graphics pipeline, a compressed z-buffer is generated for the primitive. A primitive mask is also generated, which indicates whether all pixels of the primitive are hidden from view. In a second pass, graphics data for a given primitive is passed through the pipeline, only if the primitive mask for that primitive indicates that some portion of the primitive is visible. Thereafter, a two-level z-test is performed on that primitive. In the two-level z-test, a first level comparison is made on groups of pixels at a time, using the compressed z-buffer created in the first pass.

International Classification:

A61B 17/03

US Classification:

606151

Abstract:

The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

International Classification:

G06T 1700

US Classification:

345428

Abstract:

A trilinear texture filtering system and method that improves the locality of texture map accesses in a multum in parvo (MIP) map so as to reduce page breaks and provide improved performance. The present invention includes a texture cache having a unique addressing and accessing scheme that allows localized reads of the texture map from each of four banks in the texture cache. This is coupled with a unique texture-mapping unit that includes a first level generator, a second level generator and an interpolator. In generating the lower-resolution texture map version, the present invention filters neighboring texels from the higher-resolution version. Thus, an n. times. n (e. g. 2. times. 2) square of texels at the higher-resolution level is reduced to a single texel at the lower-resolution level. This technique permits the lower-resolution level to be derived without requiring additional read operations from texture memory with potentially poor locality.
