Efficient Data Driven Run-Time Code Generation

Knowledge of data values at run-time allows us to generate better code in terms of e#ciency, size and power consumption. This paper introduces a low-level compiling technique based on a minimal code generator with parametric embedded sections to generate binary code at run-time. This generator called a "compilet" creates code and allocates registers using the data input. Then, it generates the needed instructions. Our measurements, performed on Itanium 2 and PowerPC platforms have shown a speed improvement of 43% on the Itanium 2 platform and 41% on the PowerPC one
