....can generally achieve most of the gain, for example the increase in initiation interval from 131 101 to 4 3 is only 2.8 . In any case, large denominators rarely occur: ffl The sum of the dependence distances in a cycle (Equation 2. 4) is generally 1, and is almost never greater than 3 [17]. Actually most loops have no cycles at all [26] ffl The number of any particular type of function unit in most current architectures is generally very small for example, the PowerPC 604 TM has 6 execution units and 4 INSTRUCTION ISSUE UNITS as detailed in Table 1.2. In this case when ....
