    In hyperthreading, the logical processors do not share registers, just function units. Thus, if one logical processor needs to multiply while the other needs to add, they may share the CPU resources simultaneously.

    This was developed in response to the observation that individual function units remained idle for multiple cycles while the current process was busy doing one kind of operation.
