Title: Program traveling information collecting system
Inventor: KAWAI ATSUO
IPC: G06F9/38
Filed: 1988-02-24
Abstract: PURPOSE:To certainly collect program traveling information by updating leading head fetching addresses whenever a signal indicating that a 2nd and subsequent instructions is executed is outputted from a processor. CONSTITUTION:When a processor 1 executes the 2nd instruction after completing a 1st instruction, the processor 1 outputs an executing instruction identification signal 105 to a traveling information collection controlling section 6 and clock signal 103 is sent to a counter 7 so as to advance the content of the counter 7 by one address. Then the processor 1 sends a traveling information collection start signal 104 to a traveling information collecting section 8 and informs the section 8 that the 2nd instruction is executed. When a branching condition is established to the 1st instruction and two instructions are fetched from a branched address by discarding the 2nd instruction, the section 6 does not send the signal 104 against the 2nd instruction. Therefore, program traveling information is surely collected.
