  • Patent number: 6217234
    Abstract: An MPEG video decompression method and apparatus utilizing a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine. Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and data in token format. A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens pertinent to that stage and for passing unrecognized control tokens along the pipeline. Reconfiguration processing circuits are positioned in selected stages and are responsive to a recognized control token for reconfiguring such stage to handle an identified DATA Token. A wide variety of unique supporting subsystem circuitry and processing techniques are disclosed for implementing the system, including memory addressing, transforming data using a common processing block, time synchronization, asynchronous swing buffering, storing of video information, a parallel Huffman decoder, and the like.

  • Patent number: 6104869
    Abstract: In a work flow system in which work defined beforehand with respect to data processing is executed by a plurality of workers in a plurality of nodes connected to each other through an information network, data processed in a branch source node is divided into split data so that the split data are distributed to some branch destination nodes. The split data processed in the respective branch destination nodes are connected as input data to be given to a connecting destination node. A work flow control engine sets data start and end positions of each of the split data, split data information, and connection data information into a dividing/connecting information table. The work flow control engine renews the data start and end positions in the dividing/connecting information table in accordance with increase/decrease of the split data processed in each of the branch destination nodes.

  • Patent number: 6070002
    Abstract: A computer system having a shared system memory, and system software in the computer system, are described herein. One or more user applications execute in the computer system. The computer system has a general purpose, shared system memory that is used for all processing, including video input/output operations and image conversion operations. The computer system also has a multimedia access and control module (MACM), which is the input/output interface between the computer system and the external world. In operation, the MACM receives, at one of its video input ports, video data comprising a video image (such as a frame or a field). The MACM stores the video image in a first buffer contained in a first buffer pool of the system memory. The first buffer pool was previously created by a user application. The user application previously associated the first buffer pool with the MACM's video input port. A video imaging and compression module (VICM) performs image conversion operations.

  • Patent number: 6029116
    Abstract: This invention presents a multi-beam baseband processor for making post-beamformation adjustments to the complex (in-phase/quadrature) pre-detection scan line samples acquired from a receive beamformer of an ultrasound imaging system. Specifically, the invention includes a programmable finite impulse response (FIR) filter and a programmable complex multiplier. The programmable filter performs signal shaping and sample-rate conversion. The signal shaping capability may be used to compensate for transducer and analog signal path responses, to increase signal-to-noise ratio (SNR) by rejecting out-of-band noise frequencies, to operate as a matched filter to the transmitted waveform shape, and to act as both a smoothing and anti-aliasing filter during rate-conversion operation.

  • Patent number: 6003129
    Abstract: A multiprocessor computer system includes a plurality of processors, called asymmetric processors, having mutually dissimilar control and data-handling characteristics. The asymmetric processors are controlled by a single operating system although the individual processors have instruction sets that are mutually independent of the other processors. The multiprocessor computer system uses a multiprocessor architectural definition of interrupt and exception handling in which a processor, called a data or vector processor, having a large machine state and a large data width detects exceptions but defers interrupt and exception handling operations to another processor, called a control processor, having a small machine state and data width. The small machine state and small data width of the control processor are well suited for executing operating system programs such as interrupt and exception handling since control programs typically involve monitoring and control of individual flags and pointers.

  • Patent number: 5991796
    Abstract: Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. The users or collaborators in a session are connected by one or more controllers in the server system. When a collaborator creates or joins a session, mobile code is transmitted from the system to the collaborator's computer to create a surrogate thereon, which monitors the collaborator's interaction with a web browser on the computer. The controllers communicate with all the surrogates of the collaborators to coordinate the collaborative browsing effort. When one of the surrogates detects a change by a collaborator of a uniform resource locator (URL), the new URL is communicated through the controllers to the surrogates of all other collaborators in the session. As such, the collaborators are able to move from one URL to another to browse information in a synchronous manner.
