Abstract

PURPOSE:To shorten the program development period of a small-size electronic computer by comparing data showing the order of processing with an address for confirmation and by counting the number of times of the coincidence between the both. CONSTITUTION:A confirmation address 100, addressed by a counting circuit 4, in an RAM1 is compared by a coincidence detection part 3 with a program address 200 where a small-size electronic computer 2 passes in executing a program. When the result of the comparsion shows the coincidence between the both, a coincidence signal 300 is outputted and used as a counting signal for the circuit 4. This coincidence signal 300 updates the contents of the circuit 4 successively and the updated contents are used as a new address to read the address 100 of the RAM1 set next. Thus, confirmation addresses are compared as many as a number preset in the circuit 4, and then the circuit 4 outputs an end signal 400 to set a break FF5. Consequently, a break signal 500 is inputted to the computer 2, which is stopped. Therefore, no error is considered to be in the program.
