PDF | Powerful branch predictors along with a large branch target buffer (BTB) are employed in superscalar processors for instruction-level parallelism.
Aug 18, 2010 · Branch predictors, and especially the BTB, are among the largest on-chip SRAM structures (after caches), and therefore are primary contributors ...
Mar 14, 2024 · The authors propose here a filtering scheme to dramatically reduce the accesses to the BTB to achieve significantly reduced energy consumption ...
In this paper, we propose a method that reduces the number of BTB accesses and abolishes the BTB tag by associating the instruction cache line and BTB entry.
