Abstract

PURPOSE: To ensure the recording of a number of branch addresses when necessary, by writing the contents of the tracing register into the fixed area within the main memory every time the writing is carried out in a fixed frequency to the tracing register group.
CONSTITUTION: The instruction read out of main memory 2 is decided to have satisfied the branch through branch instruction deciding circuit 4 and branch satisfaction deciding circuit 7. Thus the output is supplied to ring counter 9 to advance the counter. Based on the contents of counter 9, the contents of instruction address register 1 is written into the selected register within tracing register file 11. Decoder 10 detects the fact that the contents of counter 9 reaches the maximum count value and then advances counter 13. Then a comparison 16 is given between the contents of counter 13 and the contents of area size register 15 which holds the maximum size of the storing area in memory 3. And in case no coincidence is obtained through the comparison, the contents of file 11 is written into memory 3 at the storing area designated by save address register 14 and via control circuit 19.
