ABSTRACT:
Systems and methods for using multiple versions of programmable constants within a multi-threaded processor allow a programmable constant to be changed before a program using the constants has completed execution. Processing performance may be improved since programs using different values for a programmable constant may execute simultaneously. The programmable constants are stored in a constant buffer and an entry of a constant buffer table is bound to the constant buffer. When a programmable constant is changed it is copied to an entry in a page pool and address translation for the page pool is updated to correspond to the old version (copy) of the programmable constant. An advantage is that the constant buffer stores the newest version of the programmable constant.
