The conditional branch has long been considered an expensive operation. The relative cost of conditional branches has increased as recently designed machines are now relying on de...
Although high branch prediction accuracy is necessary for high performance, it typically comes at the cost of larger predictor tables and/or more complex prediction algorithms. Un...

Current processors exploit out-of-order execution and branch prediction to improve instruction level parallelism. When a branch prediction is wrong, processors flush the pipeline ...
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...
Code placement techniques have traditionally improved instruction fetch bandwidth by increasing instruction locality and decreasing the number of taken branches. However, traditio...
