APPARATUS AND METHOD FOR ROUNDING A FLOATING-POINT VALUE TO AN INTEGRAL FLOATING-POINT VALUE |
摘要 |
Processing circuitry is provided to perform an operation FRINT for rounding a floating-point value to an integral floating-point value. Control circuitry controls the processing circuitry to perform the FRINT operation in response to an FRINT instruction. The processing circuitry includes shifting circuitry for generating a rounding value by shifting a base value, adding circuitry for adding the rounding value to the significand of the floating-point value to generate a sum value, mask generating circuitry for generating a mask for clearing fractional-valued bits of the sum value, and masking circuitry for applying the mask to the sum value to generate the integral floating-point value.
