Operating variable's data square root value determining method for computer system, involves determining indices based on preset index range, on preset value range, on determined data of variable and on word width

摘要

The method involves determining data of an operating variable within a preset value of range. Indices are determined based on a preset index range, on the preset value range, on the determined data of the variable and on word width, where each index indexes an output value of a specific value table. The output value is determined based on the indices. A square root value of the data of the variable is determined based on the output value, a preset transformation factor, and an output value range of the output value. An independent claim is also included for a device for determining a square root value of data of an operating variable in computer system.
