Abstract
A method and apparatus for generating a zero flag (z-flag) status signal in a microprocessor includes a z-flag signal generator that generates a z-flag signal from unaligned data simultaneous to the load alignment of such data. The z-flag generator first performs a zero detect on each byte of data retrieved from memory. The zero detect results are next decoded according to bit selection signals generated from a data format code which corresponds to the specific format of the retrieved data.
