Abstract: A multiprocessor data processing system comprises a plurality of unsymmetrically connected data processing nodes; where the total number of nodes is more than 2.sup.n-1 and less than 2.sup.n, and n is an integer larger than two Each node has n input/output channels which respectively are channel(0), channel(1), channel(2), etc.; each node has a binary address b.sub.n-1. . . b.sub.1 b.sub.0 which runs consecutively from node to node; each pair of nodes whose binary addresses differ by only one binary bit b.sub.x are interconnected by a channel(x) to channel(x) connection; and, at least one pair of nodes whose binary addresses differ by two binary bits b.sub.x and b.sub.y are interconnected by a channel(x) to channel(y) connection, where x and y=0,1, . . . n-1. To establish a route from any one node to any other node, channels are selected which decrease the distance to the destination by two nodes or one node or maintain the same distance.

Abstract: This invention is an improvement to an integrated circuit package which is of a type that includes a package body with multiple chip attach regions for holding respective integrated circuit chips, signal pads around the chip attach regions, an array of I/O pins on the package body, a first set of conductors in the package body which selectively connect some of the signal pads to the I/O pins, and a second set of conductors which selectively connect some of the signal pads to each other but not to any I/O pins.

Abstract: Ragged vertical edges normally displayed by a NTSC color-carrier on a non-interlaced display are effectively eliminated through persistence of vision by altering the duration of a selected single scan-line of the non-display portion of each of successive fields by an odd number of half-cycles of the NTSC color-carrier frequency.
