SAGA: the first general-purpose on-line arithmetic co-processor

In this paper, we present a VLSI realisation of an on-line arithmetic co-processor that implements a novel algorithm known as BKM. The obtained circuit computes the complex exponential or logarithm functions. All basic mathematical operations can hence be computed. The obtained circuit might be considered as the first on-line arithmetic co-processor. The chip was designed using a specific CMOS on-line library, a generated decision and control part and some full-custom blocs
