Abstract

PURPOSE:To realize a tracing function through simple operation and to improve economy and reliability, by adding a tracing program and a few functions to a microprogram control system data processor. CONSTITUTION:When a tester puts a tracing function into effect, the storage address of an instruction to be trapped in a main storage device is stored in an instruction address strap register 1 from a console 3 and the starting microaddress of a memory 7 is stored in a microprogram jump-destination address register 4 from the console 3; and then an instruction In is stored in an instruction register 8 by setting a key K for trap indication to perform the tracing function, so if any control data is not inputted, the execution of a program which corresponds to the instruction to be trapped is interrupted and a tracing microprogram is executed according to the contents of the jump-destinated address.
