PROCESS SYNCHRONIZING CIRCUIT

摘要

PURPOSE:To always make the best use of the parallel executing possibility of programs and to increase the executing speed, not by fixing but changing dynamically the starting sequence of each processor of multi-processor system. CONSTITUTION:A process synchronizing circuit consists of block elements distributed in an matrix of (nXn). A register control line RG is turned on with block elements (i, j). Then an end signal line TKNi to a process (i) is turned on; and a firing signal line FIFEj to a process (j) is also turned on. Therefore the connecting relation is set to a start factor storing flip-flop 11 to the process (j). When a process start request flip-flop 12 is set with the line TKNi turned on, a driving transistor (TR) 14 is turned off. When all TRs 14 are turned off, the process (j) is started via a tristate buffer 25.
