Hauser. This work was made possible in part by the 18 International Computer Science Institute, located at Suite 600, 1947 Center 19 Street, Berkeley, California 94704. Funding was partially provided by the 20 National Science Foundation under grant MIP-9311980. The original version 21 of this code was written as part of a project to build a fixed-point vector 22 processor in collaboration with the University of California at Berkeley, 23 overseen by Profs. Nelson Morgan and John Wawrzynek.
