In subject area: Computer Science 'Loop Unrolling' refers to a loop transformation technique where the loop body is repeated a certain number of times to reduce the loop iteration space. This optimization method increases parallelism and allows for other optimizations in the loop body. ...
When dynamic loop pipelining is used in conjunction with static loop unrolling, the improvement in performance ranges from 6X to 20X (in terms of number of clock cycles needed for the computation) across the loop kernels that we have studied. These optimizations do have a hardware overhead, ...
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 ...
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
Verilog-to-Routing (VTR) is a Computer-Aided Design (CAD) flow. It transforms synthesizable Verilog into a placed and routed configuration for a Field Programmable Gate Array (FPGA) architecture specified in XML. The front end of the VTR CAD flow is Odin II. Odin II parses Verilog files ...
Loop transformation refers to a set of techniques used in computer science for performance optimization and code obfuscation. It includes methods like loop unrolling, loop tiling, and loop fission to enhance code efficiency and increase structural complexity. ...
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 ...
