Title:
DIGITAL CONTROL ARITHMETIC SYSTEM
Document Type and Number:
Japanese Patent JPS6186806
Kind Code:
A
Abstract:
PURPOSE:To improve the efficiency of a sampling action by changing the definition and the time needed for an operation at every time the contents of the operation are changed and calculating the total operation time of a changed operation to decide a new sampling cycle. CONSTITUTION:An operation executing means 2 executes repetitively a prescribed operation defined by an operation defining means 5 at every time an interruption is applied from a sampling command means 1 in a prescribed sampling cycle. When the operation defined by the means 5 is changed by an operation change command means 4, the time needed for operation which is stored in a memory means 3 is also changed. Then a sampling cycle calculating means 6 decides the new sampling cycle based on the total operation time of the changed operation. This new sampling cycle is informed to the sampling command means 1. In such a way, an operation is always carried out in an optimum sampling cycle despite the change of the operation.
