ECE 66300 - Compiler Code Generation, Optimization, and ParallelizationCredits: 3
Areas of Specialization(s):Computer Engineering
Normally Offered: Spring - even years
This course presents the concepts needed to design and implement production quality code generators for any of the more popular languages and families of computer architecture (including various pipelined and macro-parallel machines). Flow analysis and concurrency detection, as well as optimizations and loop and irregular code parallelizations, are covered in detail. Using C on ECN UNIX, each student will complete a project implementing a simple optimizer/parallelizer.
Required Text(s): None.
Recommended Text(s): None.
