Software-Controlled Operand-Gating
Operand gating is a technique for improving processor energy efficiency by gating off sections of the data path that are unneeded by short-precision (narrow) operands. A method fo...

The Accuracy of Initial Prediction in Two-Phase Dynamic Binary Translators
Dynamic binary translators use a two-phase approach to identify and optimize frequently executed code dynamically. In the first step (profiling phase), blocks of code are interpre...

Using Dynamic Binary Translation to Fuse Dependent Instructions
Instruction scheduling hardware can be simplified and easily pipelined if pairs of dependent instructions are fused so they share a single instruction scheduling slot. We study an...
