Manner and the device which restore predicative register set

摘要

(57) Abstract This invention offers manner and the device which restore predicative register set. One execution configuration of this invention, in order to run the restore manipulation in regard to a certain predicative register set, the 1st instruction which is specified (instruction set) includes the phase which is decoded. Responding to 1st instruction, you use the mask, you choose the multiple predicative registers which it restores (the mask). The mask of this invention consists of 1st bit set, each bit of this 1st bit set corresponds to the register which is in the midst of predicative register setting. When the bit which has 1st bit set is set to 1, the predicative register which corresponds to that bit restores. When with one execution configuration, as for this mask, 1 bits which correspond to the multiple registers which are in the midst of predicative register setting furthermore are included, this bit is set to 1, the multiple registers which correspond to this bit restore (restore unit).
