Abstract
A processor according to the present invention includes a decoding unit, an operation unitand others. When the decoding unitdecodes Instruction vcchk, the operation unitand the like judges whether vector condition flags VC˜VC() of a condition flag register (CFR)are all zero or not, and (i) sets condition flags Cand Cof the condition flag register (CFR)to 1 and 0, respectively, when all of the vector condition flags VC˜VCare zero, and (ii) sets the condition flags Cand Cto 0 and 1, respectively, when not all the vector condition flags are zero. Then, the vector condition flags VC˜VCare stored in the condition flags C˜C
