Understanding the C2H View

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.
