One of the problems in the multi-pipeline design is the limited inherent instruction level parallelism (ILP) available in applications. The ILP of application programs can be improved via a compiler optimization technique known as loop unrolling. In this paper, we present how loop unrolling effects...
Loop unrolling is, perhaps, the oldest, simplest, and best-known loop transformation. To unroll a loop, the compiler replicates the loop's body and adjusts the logic that controls the number of iterations performed. To see this, consider the loop nest from used as an example in Section ...

Loop splitting can be also used to create prologues and or epilogues of a loop (in this case it is similar to loop peeling) as in the case of loop vectorization when the iteration space is not a multiple of the vector length, or in the case of loop unrolling when the iteration space ...
Yes, unrolling the outer loop will create a multiple-compute-unit-like design; however, you will likely not get much of a performance improvement. The memory controller on the FPGA is extremely inefficient for random memory accesses and due to lack of a proper cache hierarch...
System and method for loop unrolling in a dynamic compiler Provided is a method for performing loop-unrolling optimization during program execution. In one example, a method for loop optimization within a dynamic compiler system is disclosed. A computer program having a loop structure is execute.....
to distribute the corresponding syntactic construct. The extraction process uses a secret key in order to recover the information loss and reconstruct the watermark. In particular, we focus on loops and we base the embedding and extraction algorithm on the semantic understanding of loop-unrolling. ...
Shift_reg is my attempt at trying to preserve the unrolling and adding the shift register at the same time by creating another nested loop. Unfortunately, the loop is still schedule with an II=5 with an "Undetermined reason" in Loop Analysis in the reports. If I get rid ...
Consider, as an example, a program containing a loop (identified as Li) we wish to tune based on the use of three compiler transformations, namely, loop unrolling, loop tilling, and loop parallelization. In this context, a configuration is specified by the tuple < Li, UF, TS, PAR > whe...
In at least one embodiment, one or more of said optimizations relate to loop and control flow optimization, and can include applying optimizations such a loop fission, loop fusion, parallelization, vectorization, unrolling, and so on. In at least one embodiment, a graph evaluator 108 uses an ...
