Modern processors use branch target buffers (BTBs) to predict the target address of branches such that they can fetch ahead in the instruction stream increasing concurrency and pe...

Recently, several loop buffer designs have been proposed to reduce instruction fetch energy due to size and location advantage of loop buffer. Nevertheless, on design complexity di...

—One step in the verification of hard real-time systems is to determine upper bounds on the worst-case execution times (WCET) of tasks. To obtain tight bounds, a WCET analysis h...

Modern embedded processors access the Branch Target Buffer (BTB) every cycle to speculate branch target addresses. Such accesses, quite often, are unnecessary as there is no branc...

Accurate instruction fetch and branch prediction is increasingly important on today’s wide-issue architectures. Fetch prediction is the process of determining the next instructi...
