Abstract

PURPOSE:To generate an interruption when an arbitrary instruction is executed, by deciding whether an interruption is generated after the execution of instruction or not through the interpretation of the content of an instruction register with an instruction decode table and transmitting an interruption signal to a processor. CONSTITUTION:An address of an instruction executed next from a processor 1 is outputted to a bus 2 and the content of said address of a main memory 5 is outputted to a data bus 3. The processor 1 outputs an instruction fetch signal 4 and reads the content of the bus 3 and the instruction is interpreted and executed. The content of the bus 3 is stored in an instruction register 6 in synchronizing with the signal 4. An instruction decode table 7 decides whether the interruption is generated after the execution of the instruction or not. If decided as the generation of interruption, an interruption signal is outputted from the table 7 to a signal line 8, and after the execution of instruction, the interruption is generated. The table 7 is rewritable and whether the interruption is generated after the execution of instruction or not can be designated arbitrarily by rewriting the content.
