Abstract

The invention discloses a method for automatically realizing instruction addressing in a pointer mode during inertial device calibration, which comprises the following steps of: A, establishing a global array variable of an instruction set structure body, and defining the size of an array according to the number of actual instruction sets; b, initializing a global variable of the instruction set array defined in the step A so as to assign each element in the array; c, defining a specific performance function instance, that is, each instruction generally has a specific performance function to be executed; and D, automatically addressing the main body part of the performance function by adopting a pointer mode, circularly traversing the global variable array defined in the step A through for, automatically finding the corresponding performance function according to the one-to-one correspondence relationship in the step B, and finally automatically skipping to the performance function instance defined in the step C for execution. Through the method, the problems of low reliability, low real-time performance and low subsequent function expandability in the instruction interaction process between the inertial measurement unit and the PC terminal during data acquisition and performance calibration can be solved.
