DYNAMIC PROGRAM LOADING SYSTEM

摘要

PURPOSE:To use a program memory effectively and execute a program more than memory capacity by loading the logical page body of the program in an external storage device into a program memory. CONSTITUTION:Processor elements 8-0-8-n receive a token sent from another processor unit through a network 7 and then perform processing according to the token to generate a result token. The result token when specifying another processor element is sent to the circuit 7. The circuit 7 sends the received token to a processor element corresponding to the receive token. Further, the circuits 8-0-8-n when requiring the page of the program that they execute sends a page request to a host computer 9. The computer 9 reads the requested page body of the program out of the external storage device DASD10 and sends it to the circuits 8-0-8-n. Thus, the program memory is utilized effectively by providing the device 10.
