20040093454, May 13, 2004

Filed:

Nov 7, 2002

Appl. No.:

10/289620

Inventors:

Peter Teng - Fremont CA, US

International Classification:

G06F013/36

US Classification:

710/310000

Abstract:

Disclosed is an apparatus and method for flexible controlling endpoint memory within an USB device. In one embodiment, the method includes a USB device receiving a first token packet from a USB host, wherein the first token packet includes a first endpoint number. The first endpoint number is stored into a first tag in memory corresponding to a first data buffer in the USB device. The USB device then receives a data packet from the USB host, wherein the data packet comprises endpoint data. The; endpoint data of the data packet is stored into the first data buffer.

International Classification:

G06F013/00

US Classification:

710315000

Abstract:

An apparatus for converting a PCI/PCI X device into a PCI-Express device. The apparatus may include a first circuit configured to receive first data, wherein the first circuit is configured to translate the first data into PCI formatted data. The apparatus may also include a PCI data bus and a second circuit coupled to the first circuit via the PCI data bus. The second circuit is configured to receive the PCI formatted data from the first circuit via the PCI data bus. The second circuit is configured to translate the PCI formatted data received from the first circuit into PCI-Express formatted data. However, the PCI data bus transmits data between only the first and second circuits.

Peter Y. Teng - Billerica MA

Assignee:

Wang Laboratories, Inc. - Lowell MA

International Classification:

G06F 906

US Classification:

364200

Abstract:

A task control method and apparatus for controlling the interactive, concurrent execution of a plurality of general purpose data processing tasks in a data processing system. The system includes a memory for storing active tasks, a mass storage means for storing inactive tasks and a general purpose CPU. Upon request by a user or by an active task, a task loader transfers a presently inactive task from the mass storage means to the memory to be available for execution. A memory manager assigns a task node space in the memory and a task manager creates a task control block for the task to be activated, assigns a task control block identification to the task control block, and writes the task control block identification into the task's task node space to link the task to the task's task control block. The task manager includes a plurality of task queues, each queue corresponding to a relative priority level for execution of the tasks, and each task control block is stored in a task queue corresponding to the task's priority level. The sequence of the task control blocks in each task queue is dependent upon the status of execution of the corresponding task.

International Classification:

H04L 1218

US Classification:

39520034

Abstract:

An apparatus and method for use in a network including source clients and viewer clients connected to one or more shared transmission media. A video server is connected to one of the transmission media and is operative to control the broadcast and storage of multiple live or previously-stored video streams. The control may be provided via remote procedure call (RPC) commands transmitted between the server and the clients. In one embodiment, a video presentation system is provided in which a video stream from a source client is continuously broadcast to a number of viewer clients. One or more of the viewer clients may be authorized by the source client to broadcast an audio and/or video stream to the other clients receiving the source video stream. In another embodiment, a multicast directory is provided to each of a plurality of viewer clients by transmitting directory information in a packet corresponding to a predetermined multicast address. The multicast directory indicates to a particular viewer client which of a number of video programs are available for broadcast to that client.

US Classification:

709231

Abstract:

In a live multicast in a LAN environment, audio and video streams are transmitted from a source station to a plurality of receiving stations. A technique is disclosed for synchronizing the audio decoder clock at each receiving station with the source station. A technique is also disclosed for synchronizing the audio and video data streams received at each receiving station.
