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...
One concept is loop optimization. This involves analyzing and restructuring loops to improve performance. Techniques like loop unrolling, loop fusion, and loop parallelization can be used to optimize loops and make them more efficient. However, these optimizations are typically handled by compilers or ...
An implementation of the proposed unrolling on the longest common subsequence problem scores a speedup of 1.14 on an IntelRTMAtom(TM) micro-architecture over traditional methods. Furthermore, it is presented how loop unrolling along wavefronts can aim in partitioning a loop nest in multiple ...
There is ever increasing need for the use of computer memory and processing elements in computations. Multiple and complex instructions processing require to be carried out almost concurrently and in parallel that exhibit interleaves and inherent dependencies. Loop architectures such as unrolling loop ...
In this paper we review main ideas mentioned in several other papers which talk about optimization techniques used by compilers. Here we focus on loop unrolling technique and its effect on power consumption, energy usage and also its impact on program sp

6. A method, as claimed in claim 1, further comprising at least partially unrolling said loop prior to performing steps (a) through (f). 7. A method, as claimed in claim 1, wherein said step identifying comprises identifying said independent instruction as an instruction which is on a pat...
this process of unrolling loops and increasing the size and complexity of loops, particularly for larger loops, may lead to inefficient execution due to the inability of the processor to store all the instructions of the loop in highest-speed cache. The loop-unrolling technique also leads to com...
