Abstract
A calculation device is provided that executes calculations within real-time restrictions. The calculation device implements a step of predicting a processing time of a calculation related to the amount and property of input data based on a prediction model; a step of adjusting the processing time by decreasing the amount of data used for the calculation or decreasing the number of iterative calculations when the processing time exceeds a time slice allocated to the calculation; a step of executes the calculation using the adjusted processing time; a step of updating, as required, the prediction model used for predicting the processing time according to the result of the calculation which is executed in a period where the calculation is not performed while implementing a change of the amount of data or the number of iterative calculations or change to an approximation.
