start a new iteration of the loop immediately after the prior iteration
completes State 0.
This is an example of an ideally-pipelined loop. Although the
C2H Compiler can pipeline many loops ideally, it is sometimes not
possible due to the lack of inherent parallelism in the code, as shown in
“Loop-Carried
Loop-Carried Dependencies
Loop-carried dependencies are data dependencies that manifest when
pipelining successive iterations of a loop. If the result of one calculation
in an iteration of the loop is used in a later iteration of the loop, then a
loop-carried dependency exists between the two operations.
