Design of a Program Linkage and Communication Mechanism for the Ge 645 Computer System

A generic technique for effecting both intra-computer and inter-computer program communications is briefly summarized. The design specification for the implementation of this technique on the GE-645 computer system is described. The structure and organization of the hardware mechanism through which the programs are linked and the necessary support software to facilitate its use are both considered. The basic feature of the technique is the insertion of a Buffer File into each data flow path from one program to another. A Buffer File Control Word containing control and state information is associated with each Buffer File. The hardware mechanism provides a capability for simultaneously manipulating up to eight Buffer File Control Words, symbolically referencing them in a program, and verifying and controlling a Buffer File's access rights.
