DAISY - Efficient Execution of Code for One Processor Type on Another
Machine Organization Accomplishment | 1996 - 2000
IBM researchers: Kemal Ebcioglu, Erik Altman
Where the work was done: IBM T.J. Watson Research Center
What we accomplished: DAISY was the first published description of how to efficiently emulate all of an instruction set architecture --including operating system, I/O, and self-modifying code -- in a different co-designed underlying architecture.
