The IMPACT Compiler Infrastructure for Future DSP/Embedded Systems

Roger Bringmann, Lucent Technologies

The IMPACT Compiler infrastructure is a new platform for developing future compilers for DSP/Embedded Systems. It contains a powerful combination of interprocedural pointer analysis and memory access analysis to enable aggressive optimization of memory references. A BDD based condition and predicate analysis enables aggressive optimization of program decision logic and program control flow. A schedule-time transformation framework allows automatic application of code optimizations that are traditionally performed by hand. A flexible intrinsic support facility allows state of the art EPIC compilers to efficiently support DSP and embedded system specific hardware features. This presentation gives an overview of these key features of the new infrastructure.
