Abstract
PURPOSE:To effectively collect the history information with a small storage capacity by pointing a partial processing action of an information processing system storing the history information within a relevant program by a software instruction. CONSTITUTION:The end address value of a storing action is obtained from the number of memory words of the history information which is designated a trace start instruction of an instruction control part 2 and the address data 53 showing the contents of an address register 5. Then the end address setting data 55 is sent from the part 2 and set at an end address register 13. A start signal 117 is outputted from the part 2 and an FF 11 is reset via an OR gate 33. Then a write signal 112 is outputted from an AND gate 27. As a result, a writing action is started for the history write data 51 received from the part 2 to a storage part 4.
