    Abstract: A video processing apparatus and methodology use a combination of a processor and a video decoding hardware block to decode video data by using a reference block cache memory to perform motion compensation decode operations in the video decoding hardware block. To improve the cache hit rate, each memory access for required reference block(s) is used to fetch one or more additional reference blocks which can be used to improve the cache hit rate with future motion compensation operations. Speculative fetch control logic selects the additional reference blocks by using a frequency history table to accumulate compared motion vector information for a current motion compensation block with motion vector information from previously processed motion compensation blocks.

    Abstract: A device is disclosed having a motion vector processing module to determine a first set of motion vectors associated with a macroblock of a video picture. A motion vector reduction module determines a second set of motion vectors, based on the first set of motion vectors, associated the macroblock, the second set having fewer motion vectors than the first set. A decode module comprising an input completes decoding of the macroblock based upon the second set of motion vectors

    Abstract: A video processing device (150) includes a bitstream accelerator module (106) and a video processing engine (108). The bitstream accelerator module (106) has an input for receiving a stream of encoded video data, and an output adapted to be coupled to a memory (112) for storing partially decoded video data. The bitstream accelerator module (106) partially decodes the stream of encoded video data according to a selected one of a plurality of video formats to provide the partially decoded video data. The video processing engine (108) has input adapted to be coupled to the memory (112) for reading the partially decoded video data, and an output for providing decoded video data.

    Abstract: A device testing apparatus and method for testing a semiconductor device is provided. For device testing, stimulus data is generated and provided to the semiconductor device, and output data of the semiconductor device is then evaluated to verify proper operation of the semiconductor device. Further, data in the semiconductor device output data space is mapped to stimulus data, and a set of stimulus data is determined based on the mapping results for further testing.

    Abstract: A computer system which is capable of transmitting information content through walls and other barriers to a remote station such as a home entertainment system. The system tests a plurality of radio frequency channels to locate a channel that is not in use. Channels that are in already in use are rejected to avoid interference with existing services. Once an unused channel is located, the computer system displays indicia of that channel to the user and transmits information content on the unused channel. The remote station receives the information content. In one embodiment, the remote station is a home entertainment system with audio amplifiers and speakers substantially larger and more powerful than those typically associated with computer systems such as personal and other computers. In this manner the audio and/or video qualities of the computer system are substantially enhanced by transmitting content to the remote system for presentation in an acoustically and/or visually enhanced environment.
