Approaching unums — •Cora S. Lüdde and Udo Kebschull — Infrastructure and Computer Systems in Data Processing (IRI), Goethe-University Frankfurt, 60629 Frankfurt am Main, Germany

A new format for numbers has been proposed by John L. Gustafson with the aim to replace the IEEE standard. The new format called unums will be presented and its advantages over the IEEE format will be illustrated.

The use of unums is supposed to save energy, to support parallelism and to prevent rounding errors. This is possible due to a specific extension of the IEEE Format and the introduction of a special arithmetic.

First application of unums has been realised with Mathematica by Gustafson.

One of our aims is to implement this new format on FPGAs, to verify the statements Gustafson made and to reproduce and hopefully improve results of preceeding calculations. Finally we expect to use the new concept for a faster processing of large quantities of data which are accumulated in high energy experiments.
