Development of a Run Time Math Library for the 1750A Airborne Microcomputer.

Abstract

This thesis produced a run-time math library for the MIL-STD-1750A embedded computer architectures. The math library consists of the circular trigonometric functions and their inverses. In addition, the steps required for the performance analysis of the math library have been outlined. Several approximation methods were investigated, but the Chebysher Economization of the Maclaurin series polynomials, and rational approximations derived from the second algorithm of Remes were determined to be the best available. Each functions implementation was designed to take advantage of features of MIL-STD-1750A architectures. The recommended test procedures will provide measures of the average and worst case generated errors within each approximation. The computer program is provided.
