    Compositional Static Cache Analysis Using Module-level Abstraction

    Static cache analysis is utilized for timing analysis to derive worst-case execution time of a program. Such analysis is constrained by the requirement of an inter-procedural analysis for the entire program. But the complexity of cycle-level simulations for entire programs currently restricts the feasibility of static cache analysis to small programs. Computationally complex inter-procedural analysis is needed to determine caching effects, which depend on knowledge of data and instruction references. Static cache simulation traditionally relies on absolute address information of instruction and data elements. This thesis presents a framework to perform worst-case static cache analysis for direct-mapped instruction caches using a module-level and compositional approach, thus addressing the issue of complexity of inter-procedural analysis for an entire program. The module-level analysis parameterizes the data-flow information in terms of the starting offset of a module. The compositional analysis stage uses this parameterized data-flow information for each module. Thus, the emphasis here is on handling most of the complexity in the module-level analysis and performing as little analysis as possible at the compositional level. The experimental results show that the compositional analysis framework provides equally accurate predictions when compared with the simulation approach that uses complete inter-procedural analysis.
