Abstract: A bi-directional global data bus scheme for use in a random access memory which optimizes the performance of the data path for read and write operations while offering a uniform read and write frequency to the external processor or controller is presented. The system makes use of a dual local data bus structure which allows the column address to change on every clock cycle since the two parallel local data paths are activated on alternate clock cycles and therefore operate at half the nominal operating frequency. For the read operation, the global data buses operate differentially at the nominal operating frequency. For the write operation, the global data buses operate at half the nominal operating frequency with each global data bus of a complementary data bus pair being dedicated to either one or the other local data paths for every other clock cycle. By implementing this scheme internally, a uniform read or write operating frequency is seen by the microprocessor, thereby simplifying its interface with the memory.

Abstract: An antenna structure is disclosed that is a loop of conductors, approximately one wavelength in perimeter, plus a supporting conductor connected from one side of the loop to the opposite side. This antenna structure is connected to the associated electronic equipment, in a balanced manner with respect to the supporting conductor, effectively at either connection between the loop and the supporting conductor. Because of the balanced connection, the supporting conductor carries very little current and has very little influence on the electrical operation of the loop. Such a structure could be made stronger than the traditional one-wavelength loops supported by insulators, because metals usually are stronger than insulating materials.

Abstract: In this picture signal converting apparatus, digital picture signals compressed in a DVC format are decoded to non-compressed picture signals of a 4:1:1 color component type which are composed of color difference signals and luminance signals. The color difference signals of the 4:1:1 color component type arranged in a matrix are removed on every other row to halve the number of color difference signals in a y direction, and a color difference signal is added to a position between each pair of color difference signals adjacent to each other in an x direction to double the number of color difference signals in the x direction. Therefore, converted color difference signals of a 4:2:0 color component type are produced from the color difference signals. Values of the converted color difference signals are determined according to values of the color difference signals.          Thereafter, the converted color difference signals and the luminance signals of the non-compressed picture signals are combined to produce converted digital picture signals of the 4:2:0 color component type.

Title: Programmable transport and network architecture

Filed: 1998-04-30
Granted: 2003-01-21
Abstract: This invention relates to the design of a scaleable high performance multiservice network based on programmable transport. A meshed network with dynamically-adjustable link capacities and nodes which provide data packing into "containers" for transport is proposed. A  ring-based network, exchanging data containers among its nodes, is the preferred implementation, due to its flexibility, maintainability, and high reliability. With lossless rings, the quality of service is controlled solely by the origin and destination nodes, without any interference from other data streams. Flexible programmable transport greatly improves the performance, simplifies the controls, and facilitates scaleability. The concept is a departure from classical network thinking. By reducing the complexity of the network core, an economical, reliable, and manageable network with feature-rich edge nodes can be realized. An architecture with recursive ring-based structures provides a high degree of flexibility in bandwidth allocation and is compatible with current transport networks and future all-optical networks.
