Abstract
PURPOSE: To find a program error by recording program execution addresses in a shift register type recording memory until a program execution address agrees with an externally set address and by externally reading the recording content.
CONSTITUTION: When an error is assumed to be generated as an advancement is made up to execution address A of a program in process of debugging, execution address A is set previously in register 5 via signal line 4 and the program is rerun. Execution address 1 of a fetched program is set in register 8 successively. Memory control circuit 13 assigns the address where execution address 1 set in register 8 is to be stored in recording memory 12 and also reads write signal 19 in sequence to write the execution address in the recording memory. Value A set in register 5 is compared to execution address 1 by comparator 9 and when their coincidence is detected, that is reported to control circuit 11.
