Randall Weinstein - Atlanta GA, US
Kirk Williams - Kennesaw GA, US

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04L012/28
H04L012/56

US Classification:

370/401000

Abstract:

A centralized concentrator for use with a computer network and a method of distributing wireless communications in a computer network employing a distributed access system. In one embodiment, the centralized concentrator includes a wireless communicator and a central protocol processor. The wireless communicator sends and receives a wireless communication to a communications network and to a wireless client access subsystem. Coupled to the wireless communicator is the central protocol processor which provides bridge functionality for the wireless communication.

US Classification:

710/113000

Abstract:

The present invention creates dedicated point-to-point or point-to-multipoint links between different devices along plural busses. In a preferred embodiment, all of the devices are on the same chip or PC board. Synchronized clocks to each device enable proper timing of read and write operations to/from the bus. The bus connection between the devices are selectively switchable so that dedicated bus connections between devices can be switched on and off as needed. Since the links are point-to-point between sending and receiving devices, the throughput of star-like topology (e.g., Ethernet) can be achieved with very low latency. An arbiter creates the link. The link is established indefinitely, for as long as the arbiter configures it to exist. Additional transactions through the link require only a frame signal to be asserted by the sender and the frame signal to be interpreted as a “data ready” signal by the target. It does not require the complex bus negotiations as required by a protocol like PCI. Multiple busses are available to the arbiter to allocate so that one device need not wait for another device to finish their transaction. Further, each bus need only run at the speed necessary for the device to which it is dedicated, thereby reducing overall power consumption.

Abstract:

An electronic device configuration that models a dynamical system can be produced by compiling program code written in a specialized modeling language into directed flow graph data, and then transforming the directed flow graph data into device configuration data. The device configuration data represents an electronic device configuration that includes an execution engine modeling the dynamical system.
