Description


A summary of more than a decade of research in the area of backend code optimization for high performance and embedded computing, this book contains the latest fundamental and technical research results in this field at an advanced level.
With chapters on phase ordering in optimizing compilation, register saturation in instruction level parallelism, code size reduction for software pipelining, memory hierarchy effects in instruction-level parallelism, and rigorous statistical performance analysis, it covers material not previously covered by books in the field. Other chapters provide the latest research results in well-known topics such as instruction scheduling and its relationship with machine scheduling theory, register need, software pipelining and periodic register allocation.
As such, Advanced Backend Code Optimization is particularly appropriate for researchers, professors and high-level Master’s students in computer science, as well as computer science engineers.
