Floating Point MATH implemented with software EMulation
Based on the SoftFloat IEC/IEEE Floating-point Arithmetic
Package, Release 2b, written by John R. Hauser.
Also uses extensions to SoftFloat, written for
Bochs (x86 achitecture simulator), by Stanislav Shwartsman.

International Computer Science Institute, located at Suite 600, 1947 Center
Street, Berkeley, California 94704. Funding was partially provided by the
National Science Foundation under grant MIP-9311980. The original version
of this code was written as part of a project to build a fixed-point vector
processor in collaboration with the University of California at Berkeley,
overseen by Profs. Nelson Morgan and John Wawrzynek. More information
