PROBLEM TO BE SOLVED: To efficiently process a floating point exception by a processor which executes an SIMD instruction.SOLUTION: Processing includes the steps of: specifying a numeral exception of an SIMD floating point operation; starting a first SIMD micro operation so as to generate a first Packed part result of the SIMD floating point operation; starting a second SIMD micro operation so as to generate a second Packed part result of the SIMD floating point operation; starting an SIMD unnormalization micro operation so as to put the first and second Packed part results together and to generate a third Packed result having an unnormalized element by unnormalizing a first element of the first and second Packed part results having been put together; storing the third Packed result of the SIMD floating point operation; and setting a flag for specifying the unnormalized element of the third Packed result to the first Packed part result. |
