Lesson 5: Writing Linear Assembly
2-28
Resource Bound is higher, this usually means we can make a better partition
by writing the code in linear assembly.
Notice that there are 5 cross path reads on the A side and only 3 on the B side.
We would like 4 cross path reads on the A side and 4 cross path reads on the
B side. This would allow us to schedule at an iteration interval (ii) of 4 instead
of the current ii of 5. Example 2–16 shows how to rewrite the iircas4 ( ) function
Using Linear Assembly.
