WebbWe consider hardware-only prefetching in this study. Prefetching can be done at any cache level. Level-1 (L1) and level-2 (L2) prefetching lead to different possibilities and tradeoffs, hence different sorts of prefetchers. An L1 prefet-cher can use some informations that it would be somewhat costly to propagate to the L2 cache, such as load ... WebbOther types of prefetchers interact with hardware struc-tures [6], [26], [30], [31], [38], such as the branch predictor (e.g. BTB directed), to gain insights into the program’s exe-cution ahead of time, however they require intrusive changes in the processor design. Typically, prior work in prefetching has adopted look-ahead

WebbGenerally, prefetching can be implemented in hardware or software. The software prefetching is normally implemented as an instruction in processors instruction (like fetch instruction). The purpose of this project is to discuss the hardware prefetching. Moreover, we present three different hardware prefetching techniques. WebbEtimología.
