Development and Evaluation of Math Library Routines for a 1750A Airborne Microcomputer.

Abstract

This project produdced a run-time math library for the MIL-STD-1750A embedded computer architectures. The math library consists of the algebraic functions. In addition, the steps required for a performance analysis of the math library have been outlined. Several approximation methods were investigated. The Chebyshev Economization of Maclaurin series polynomials, and rational approximations derived from the second algorithm of Remes were determined to be the best methods available. Each function's implementation was designed to take advantage of features MIL-STD-1750A architectures. The recommended test procedures provide measures of the average and worst case generated errors within each approximation. (Author)
