Abstract
PURPOSE: To enable the addressing of a memory space more than logically-prescribed one by giving each word in a main memory an extra address trap assignment bit and an extra store trap assignment bit.
CONSTITUTION: Into central controller 2 constituting the trap control circuit, main- memory address register 3, buffer register 4, instruction address register 5, trap address register 6, and system control register 7 are provided. In addition, the controller is equipped with interruption cause register 8, general register groups 9 to 10, arithmetic circuit 11, trap control circuit 12, and trap interruption signal control circuit 13. In order to control controller 2, main-memory buffer register 14 is provided externally and both store trap detection signal 14a and address trap detection signal 14b are applied from the controller to trap control circuit 12. In this way, addressing is attained and many traps can be applied simultaneously.
