PROBLEM TO BE SOLVED: To provide an information controller which uses a buffer memory that has less capacity and collects execution history of a program. SOLUTION: In this device, a task information preserving part 1 counts an execution clock of a task, a task information processing part 2 acquires task information consisting of an execution clock number and the number of execution of a task from the part 1 in a timing when tasks are changed, adds the task information by fetching the content of a buffer address to the task from a task information storage buffer 3 and stores only task information of each task in the buffer 3. Thus, only the capacity for task information quantity per the number of executed tasks×one occupies a memory, and the execution history of a program can be collected by using a buffer memory of less capacity.
