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