As of 2014, version 2 of the user space ISA is fixed.[19] The ISA is designed to be extensible from a barebones core sufficient for a small embedded processor to supercomputer and cloud computing use with standard and chip designer defined extensions and coprocessors. ./cache/en-wikipedia-org-5744.html ./txt/en-wikipedia-org-5744.txt
