Method to design delay by software for short times,using models and mathematical methods,to obtain the algorithm with exact times.

Abstract

This article shows an algorithm that determines the constants necessary to achievethe time accuracy of a delay by software routine called delay by sums, for use with embeddedprocessors or systems. The algorithm demonstrates the methodology to achieve accurate times and concludes with the obtaining of a linear equation of first degree with three unknowns, from which these values can be obtained; however, the equation obtained requires a special procedure to determine the value of each of the variables, which is described in this paper.
