Ideograph is a truly unifies data and procedural dependencies. Ideograph can be used to assist various program optimization, such as common expression elimination, code motion, constant folding etc. In this paper, we propose an improved representation of the data and control flow dependencies information for the efficient program execution. In pursuing this goal, we propose a model and in particularly implement a dependency information extractor and information table, which contains data and control flow information per a basic block And then we design and implementation of the optimized abstract syntax tree using Ideograph which has a control flow information and data flow information for source program.
