Abstract

PURPOSE:To realize a high-speed sampling, by providing a direct task, which is not controlled by the OS, and a timer which prescribes the sampling period and outputting a task start signal from the input/output device for the input of a process state. CONSTITUTION:An OS start level interrupt signal 14 which is outputted from a process 1 through a process input/output device or is outputted from an operation panel 17 starts an OS 15 first, and the OS 15 starts general tasks 19 under its control. Meanwhile, a direct task start level interrupt signal 13 which is outputted from the process 1 through the process input/output device drives hardware in a level higher than that for the OS 15 to start a high-speed sampling task (HSS) 18, which is not under the control of the OS 15, without intervention of the OS 15. In figure, 18 and 20 indicate the sampling task and an information processing task respectively.
