Compilation for Predictable Real-Time Systems

CPS: Ao.Univ.Prof. Dipl.-Ing. Dr.techn. Peter Puschner, 01. 03. 2010

Usually, the focus of compiler writers is to generate fast code. Contrasting this, the goal of this thesis is to work on code generation strategies that produce code with predictable timing, i.e., the stability of the timing and a simple prediction of the worst-case execution time are in the center of interest.


Predictable Cache Memory

CPS: Ao.Univ.Prof. Dipl.-Ing. Dr.techn. Peter Puschner, 10. 03. 2006

Cache memories are used to boost the performance of computer memory systems. While the performance benefit of caches is indeed substantial, the use of caches makes the calculation of the run times of code very difficult. The goal of this work is therefore to conceive a new type of hierarchical memory system, that allows for both, a high performance of program execution and a good predictability of code timing.


Limitations on the Analyzability of Real-Time Systems

CPS: Privatdoz. Dipl.-Ing. Dr.techn. Raimund Kirner, 08. 03. 2006

To operate real-time sytems in a safe way, it is required to know the maximum execution time of the program code. However, there are problems to reason about the program behavior in general (c.f., the Halting Problem).

It is the goal of this work to analyze the problem from the other side, i.e., by analyzing what code structures are predictable. For this one has to also look on program analysis methods to reason about what properties can be derived by such an analysis. It is the goal of this work to find restrictions on the program structures, such that the execution time analysis becomes feasible.
