Latest Patents

Chung's latest patents include a "Programmable 3D Graphics Pipeline for Multimedia Applications." This invention features a programmable graphics pipeline and a method for processing multiple partitioned multimedia data, such as graphics, image, video, or audio data. A preferred embodiment of this pipeline includes an instruction cache, a register file, and a vector functional unit that performs partitioned instructions. Additionally, an enhanced rasterization unit generates inverse-mapped source coordinates alongside destination output coordinates for graphics and other media processing. An enhanced texture address unit generates corresponding memory addresses of source texture data for graphics processing and source media data for media processing. Data retrieved from memory are stored in an enhanced texture cache for use by the vector functional unit.

Another notable patent is the "Processor Employing Loadable Configuration Parameters to Reduce or Eliminate Setup and Pipeline Delays in a Pipeline System." This deep-pipeline system significantly reduces the overhead of setup delays and pipeline delays by dynamically controlling access to multiple configuration register sets by both a host central processing unit (CPU) and the stages of the pipelines. A master configuration register set is loaded with configuration parameters by the host CPU in response to an index count provided by a setup-index counter. A plurality of other counters track timing events in the system, enabling efficient processing of tasks.
