Scheduling Information Per Assignment
Typically the number of assignments in a loop is fewer than the number
of states mapped for the hardware state machine that controls the loop.
When there are fewer assignments than states, this method of interpreting
the scheduling information is often easier.
In Example 4–2 , there are four assignments in the loop. This section
displays all of the assignments whether they occur on states that are a part
of the critical path or not. As shown in the previous section the CPLI of
this loop is six due to the critical path variable
crc . Figure 4–7 illustrates
the information shown when the example is compiled.
Figure 4–7. CRC Scheduling Per Assignment
Using the methodology from “Cycles Per Loop Iteration (CPLI)” , you can
create a chart such as Figure 4–8 , corresponding to Example 4–2 on
page 4–10 .
