Method and apparatus for a rearrangeably non-blocking switching matrix

A switching apparatus is disclosed that employs a relatively simple and inexpensive switching matrix, but which avoids interruption of existing connections when connections are added or removed. The switching matrix switches errorlessly by controlling the point in time at which switching occurs. Using such a technique, switching can be performed without disturbing the connections already configured in the switching matrix, and so is referred to herein as being non-blocking. Optionally, the incoming data can be rearranged to provide a larger window of time in which the switching matrix can be switched. In the case of a switch using an optical backplane, this also allows more time for various components of the system (e.g., clock / data recovery units) to re-acquire lock. The switching apparatus includes a switching matrix and control circuitry. The switching matrix has a matrix input, a control input and a number of matrix outputs, and is configured to receive an information stream at the matrix input. The information stream includes a number of portions, while the control circuitry has a control output coupled to the control input. The control circuitry is configured to initially configure the switching matrix to output the information stream at a one of the matrix outputs and to subsequently configure the switching matrix to output the information stream at another of the matrix outputs during a period of time during which the one of the portions is transiting the switching matrix.

Optical communication system and method using spread-spectrum encoding

InactiveUS20050019040A1High levelIncreasing optical bandwidthElectromagnetic transmittersOptical communicationComputer science
Using spread-spectrum encoding the spread the spectrum of information signals transmitted in an optical communications system enables significantly higher levels of inter-channel interference to be tolerated than in conventional optical communication systems. This allows the bandwidth of the optical channels of the optical communication system to be increased, and the bit rate of the channels to be increased. Applying spread-spectrum encoding to the information signals increases the bit rate of each information signal by a factor of L, but significantly more than L spread-spectrum information signals can be transmitted in the same optical channel and can be successfully recovered at the receiver. Accordingly, using spread spectrum encoding provides a significant increase in the capacity of the optical communication system.

The present invention discloses a data scheduling and transmitting method supporting a time trigger mechanism in a FC switch, including the steps as follows: performing parameter configuration for a port of the switch according to a virtual channel strategy; 2. judging whether a data frame is time trigger data or event trigger data after the port of the switch receives the data frame, and entering a time trigger buffer region if the data frame is the time trigger data; 3. querying the message cycle and the time migration according to a virtual link number after the time trigger data enters the time trigger buffer region, judging whether the data frame is valid or not according to the current global time, and putting the data frame in a port buffer region if the data frame is valid and transmitting a schedule request to a scheduler; 4. responding the schedule request by the scheduler at the given time; 5. and switching on a crossbar switch by the switch after the schedule success so as to complete the data exchange and transmission. The method meets the requirements of high bandwidth and real-time performance for communication transmission in the airplane avionics system.

Sparse neural network processor based on systolic array

The invention provides a sparse neural network processor based on a systolic array. The sparse neural network processor comprises a storage unit, a control unit, a sparse matrix operation array, a calculation unit and a confluence array. The storage unit is used for storing weights, gradients, features and instruction sequences used for scheduling data streams. The control unit takes out data required by the training and reasoning process from the storage unit according to the control of the instruction sequence, converts the data into a sparse matrix operation format and sends the data into the sparse matrix operation array. The sparse matrix operation array comprises a plurality of processing units connected in a systolic array mode and is used for completing sparse matrix operation. Thecalculation unit is used for completing element-by-element operation such as a nonlinear activation function. The confluence array delivers the same data segment to different rows of the systolic array through internal data transfer to reduce storage overhead. The processor makes full use of the sparsity of the weight and the characteristics, achieves the improvement of the speed and power consumption ratio in the neural network training and reasoning process, and has the advantages of high concurrency, low bandwidth requirements and the like.

Network security device

Methods and apparatus, including computer program products, implementing and using techniques for processing a data packet. An input port receives a data packet, a switching board classifies the data packet, determines whether the data packet should be accepted, and switches the data packet to a management board if the data packet is a first data packet in a session, and to a processing board if the data packet is not a first data packet in a session. A management board receives a data packet from the switching board, examines the data packet and forwards the data packet to one of the processing boards. One or more processing boards receives non-first data packets from the switching board and data packets from the management board and processes the data packets. A firewall and a secure gateway with firewall and virtual private network functionality for processing a data packet are also described.

System and method for generating digital data and processing in a memory

In a video conferencing system, digital data representing pixels of a selected scene are stored in a Video accumulator Array Memory cells (VAM), each cell having memory with several register structures and having the capability of processing the digital data to facilitate compression of the digital data. The VAM has the ability to tell the processor information about the temporal nature of the video data without requiring the processor to first read the data and then test the data. In accordance with the present invention, the capability of processing the video data is designed directly in the memory function as they are stored. The memory array, by providing a capacity of temporal processing wherein the digital data in one video frame can be logically interacted with another video frame later in time, can make a significant reduction in the bandwidth required to transmit a video frame. In a scheme for representing gray scale luminosity, the luminosity is digitally represented by the plus and minus differences from the mid point of the gray scale. A color video camera, in addition to generating color separation pixel values, also generates gray scale luminosity values which include a steady state infrared component provided by steady state illumination of scene in order to reduce the adverse effects of fluorescent lighting.
