C Compilers for ASIPs: Automatic Compiler Generation with LISA • Presents a strong background and various perspectives of architecture description language (ADL)-based processor design and the retargetable compilation problem; • Provides the history of ADL based processor design, making the reader knowledgeable about the past research as well as the difficulties faced over time; • Offers an ADL based modelling formalism and corresponding implementation methods, which can be used for automatic compiler retargeting to quickly obtain compiler support for newly developed ASIPs; • Presents retargetable optimization techniques for common ASIP features, which can be quickly adapted to varying target processor configurations and help to meet the stringent performance requirements of embedded applications.
