International Classification:

G06F 1516

US Classification:

710110, 710108, 709213, 709216, 711152, 711163

Abstract:

A computer system provides a self-modifying synchronization memory address space and protocol for communication between multiple busmasters. In one computer system embodiment, the self-modifying synchronization memory address space is provided in a memory controller embedded in a peripheral device of the computer system such as a bridge that provides central, high speed access by a busmaster to the memory controller without accessing a host bus. The synchronization memory address space includes a set of semaphore memory cells mapped to shared critical resources in the computer system. The semaphore memory cell allows for exclusive access by a busmaster to a shared critical resource by switching itself from an idle state to a busy state responsive to a first read operation by a busmaster. In the busy state of the semaphore memory cell, a busy state is communicated to other busmasters which attempt to read the semaphore memory cell. Ownership of the semaphore memory cell is thus achieved using a single operation by a busmaster.

International Classification:

G06G 536

US Classification:

345605, 345549, 345545

Abstract:

In storing data for display, traditionally twenty-four bit video pixels have required extra video memory to store the video pixels on double word boundaries or extensive hardware to fully utilize video memory. Eight twenty-four bit video pixels are stored within three quad words in a manner that reduces the required hardware from prior approaches and fully utilizes video memory.

International Classification:

H04N 7/01
G06F 13/16

US Classification:

348725, 345521

Abstract:

A digital television/local bus interface logic supports handling of digital television (DTV) data with non-tearing. The interface logic provides a dual frame buffer DTV architecture in which a pair of DTV/local bus frame buffers alternate functions: one frame buffer stores incoming DTV data and the other frame buffer stores the outgoing DTV data. When a refresh of a display device reaches a programmed position of the display device, the interface logic determines which frame buffer is being updated by the incoming DTV data. The outgoing DTV data is then read from an opposite frame buffer and transmitted to the display device. The interface logic receives a horizontal sync signal and a vertical sync signal from the graphics controller for monitoring refresh of the display device. The interface logic also provides an architecture for transferring decoded DTV data over a local bus to the graphics controller.

Assignee:

Breakingpoint Systems, Inc. - Austin TX

International Classification:

H04J 1/16

US Classification:

370231, 370235

Abstract:

A network processor is enabled to retrieve a packet transmission data structure (PTD) from a memory. The NP parses packet data from the PTD and transmits the data over the network as a network packet. The PTD may include repetition information used by the NP to transmit a plurality of packets. The PTD use transmission interval information to control transmission timing of consecutive network packets. The PTD may include modification information used to modify the data packet portion. The modification may include incrementing, decrementing, or storing a random number into any portion of the data packet. The PTD may include flow control information to determine the next PTD to process. The flow control information may include criteria including acknowledgement criteria and time delay criteria. The packet data portion preferably includes all formatting information applicable to the network.

International Classification:

H04L012/28
H04L012/56

US Classification:

370/389000

Abstract:

A network or other type of processor operates to switch packets from an incoming cell stream to an outgoing cell stream. Each received and transmitted cell in a cell stream includes portions of packets, or complete packets or both. Packets are reassembled from incoming cells, and outgoing cells may be created from portions of packets, complete packets or both. The packets in the outgoing cells may be from incoming packets, switched reassembled packets or both. Each incoming and outgoing cell is associated with one virtual channel, and each virtual channel for an outgoing cell may be different from the virtual channel corresponding to the incoming cell or cells from which a packet was reassembled. Switched packets also may have their conversation identifications changed. Partial packets or partial cells that are awaiting completion are retained such that switching capabilities associated with the virtual channel and channel identification modifications may be used.

US Classification:

370252

Abstract:

An automated method for analyzing a plurality of network messages received by a network testing device is disclosed. The method may comprise, during a current window of time, receiving from a target network device a network message associated with an original network message determining a latency value for the received network message comparing the determined latency value with the threshold latency value; and incrementing either the first counter or the second counter based on the comparison of the determined latency value with a threshold latency value. The method may further comprise, at the end of the current window of time, storing the first and second counter values resulting from the analysis of the plurality of original network messages.
