PURPOSE:To attain collection of lots of phenomena with simple circuit constitution. CONSTITUTION:A data collecting device for measuring the performance of a computer has an RAM5 as a storage means storing sequentially the signal state of each part of the computer, an address counter being a means storing the addresses of the RAM5 updating the addresses, and a detecting means 7 detecting the end of storage to all addresses of the RAM5 and generating an interruption signal to a micro program. Further, the micro program 8 controls, e.g., a device to be measured normally and consists of a collecting means 9 reading and accumulating information stored in the RAM5 in the ascending order of addresses at any time and an initial set means 10 keeping an address counter 6 to the initial state after the logging is finished. |
