While delayed branch mechanisms were popular with the designers of RISC processors, most superscalar processors deploy dynamic branch prediction to minimise run-time branch penalties. We propose a generalised branch delay mechanism that is more suited to superscalar processors. We then quantitatively compare the performance of our delayed branch mechanism with run-time branch prediction, in the...

Complete right bundle-branch block with right axis deviation was seen in nine patients who did not have right ventricular hypertrophy, pulmonary disease, or extensive lateral myocardial infarction. Four patients had chronic block and five had acute myocardial infarction. This pattern was attributed to a coexisting block in the right branch and in the inferior division of the left branch. It fre...

We propose an alternative approach to branch resolution based on the earlier work on decoupled memory architectures. Branch decoupling is a technique to decouple a single instruction stream program into two streams. One stream is solely dedicated to resolving branches as early as possible (both the branch condition and the branch target). The resolved branch targets are consumed by the other co...

Experiments to determine the potential for program-level and/or phase-level adaptation of branch predictor configuration for the purpose of total processor energy savings were performed. The performance and energyefficiency of an 8-wide issue, out-of-order processor with six different branch predictors were evaluated on the SPECcpu2000 benchmark suite. Each branch predictor was compared to the ...

Provisional side-branch stenting is currently the most widely accepted percutaneous technique for the treatment of bifurcation lesions. However, abrupt closure of the side branch may occur after main vessel stent implantation. Resolving side-branch stenosis under these conditions may pose major technical difficulties. We describe a new technique to resolve uncrossable side-branch occlusion foll...

We define branch products relations, a new product construction. Branch product relations generalize direct products, lexicographic products, and ordered sums. We investigate criteria for various properties of relations to be preserved by branch products, focusing on branch products over trees. Among our nicer results are the preservation of poset dimension and various order-completeness proper...

To study the effect of different branch configuration on transmission characteristic in-home lowvoltage (LV) communication power line communication (PLC) channel, the influences of branch length, number of branch and tap, and branch terminal impedance on the performance of PLC are investigated. The two type power line network structures of the one-tap with multi-branch (OTMB) and the multi-tap ...
