摘要： A ring configurator for interconnection of data processing and communication systems uses fully covered rings. The ring configuration mechanism can be used to construct a set of covering rings preserving full connectivity for system interconnect. The mechanism can also be used for establishing the routing table for each interconnected system during the system initialization time. To generate a set of edge-disjoint rings, a rotational mechanism is used. The rings are considered stretching along a horizontal direction with nodes aligned in columns across all the rings. With a proper relabeling of the nodes, nodes appearing in the same column position of each ring can be obtained by a simple rotation of the nodes from the previous column of the rings. Once the rotational position is determined for each column, a set of N-1 edge-disjoint rings can be constructed. To find an extra ring so that when combined with the N-1 rings thus found the ring constraints are satisfied, a node reduction technique is invoked. The procedure can be repeated until a set of N edge-disjoint rings satisfying the constraints are found.

摘要： A method for noise removal filtering is provided. The method includes selecting a characteristic of a test pixel, such as brightness, and comparing the brightness of the test pixel to the brightness of an adjacent pixel. The noise removal filtering is terminated if the test pixel brightness is equal to the adjacent pixel brightness, such that it can be determined that the test pixel has not been corrupted with noise data.

摘要： Packet-Based Direct Memory Access. The present invention overcomes the oftentimes hardware consumptive and complex implementation of conventional direct memory access (DMA) that employs descriptors. The descriptors that must are employed by conventional DMA must be set up by software, and the handshaking between the hardware and software is typically very cumbersome. The packet-based DMA performed in accordance with the present invention is operable and adaptable to various types of cell-based DMA modes. A flow control regulator, or flow control state machine, is used to control the packet-based DMA performed in accordance with the present invention. Two different multiplexors (MUXs) are employed, one for each of the transmit and the receive packet-based DMA transfers, to select the various cases of packet-based DMA. The present invention is operable within various modes including asynchronous transfer mode (ATM) cell-based asynchronous digital subscriber loop (ADSL) applications. An efficient implementation using registers to control the packet-based DMA transfers is provided by the present invention.
