INTERCONNECTING NETWORK AND ITS CROSS BAR SWITCH

Title:

INTERCONNECTING NETWORK AND ITS CROSS BAR SWITCH

Document Type and Number:

Japanese Patent JPH01131950

Kind Code:

A

Abstract:

PURPOSE:To prevent the contention for another relay path from being generated at the time of relaying and to completely eliminate the risk of dead lock b using a cross bar switch as a relay means annexed to an element processor. CONSTITUTION:An arbitrary element processor P(i,j,k) arranged logically at each lattice point corresponding to the inner point of a rectangular parallelopiped of (LXMXK) on a three-dimensional grid space is connected to three cross bar switches 9-1-9-3. Each cross bar switch is provided with a function to communicate with the element processor having a number in which the coordinate value of one specific dimension of a three-dimensional coordinate constituting a processor number is substituted by another coordinate value. Therefore, it is possible to communicate with the element processor having any number by relaying three coordinate transform cross bar switches, and the dead lock can be prevented from being generated completely by using a relay cross bar switch.
