10International Computer Science Institute, located at Suite 600, 1947 Center
11Street, Berkeley, California 94704. Funding was partially provided by the
12National Science Foundation under grant MIP-9311980. The original version
13of this code was written as part of a project to build a fixed-point vector
14processor in collaboration with the University of California at Berkeley,
15overseen by Profs. Nelson Morgan and John Wawrzynek. More information
