Abstract
This chapter presents two types of algorithms for computations with limited resources, the shift-and-add and the CORDIC algorithms. The algorithms allow the computation of elementary functions such as the logarithm, exponential function, sine, cosine and their inverses with only shifts, adds, comparisons and table lookups.Some early oating-point units (FPUs) used CORDIC algorithms and your pocket calculator surely does.
