Handling cache in real-time scheduling

This is the report describing works in the research topic: ”Handling cache in real time schedul-ing simulation ” during the 6 month internship at Lab-STICC, CNRS, UMR 6285, University of Western Bretagne, in the context of SMART project and Cheddar tool set. Cheddar implements a simulator of real-time systems. This simulator allows architecture designers to model a real-time system and to investigate its behaviour [1]. The framework of SMART project includes a complex hardware platform with multi-core processor and multi-level of cache system, which is need to be verified. However, the current object models in Cheddar does not support simulation of this architecture. In the work, there are three important achievements. The first achievement is to model and im-plement the cache systems in the Cheddar. The second achievement is to model the task’s cache related behaviours and implement the model. The third achievement is to implement cache anal-ysis and provide statistics in the process of scheduling analysis or feasibility test. Developments and improvements for the cache analysis can be made in order to adapt with the various type of caches and system configurations
