Description de l'offre
Your involvement in this project will facilitate the creation of a predictability toolbox that streamlines the exploration of design trade-offs, ultimately leading to the production of highly tailored RISC-V processors designed for Internet of Things (IoT) applications and embedded platforms used in safety-critical systems. A key aspect of predictability analysis involves assessing the worst-case execution time (WCET) of a processor by examining how a given binary code progresses through successive pipeline stages. Timing Anomalies (TAs) are execution phenomena known to hinder these analyses and must be supported.
Your main responsibilities will include:
• Proposing and developing an approach to generate formal models of processor pipelines. This involves utilizing a cycle-accurate intermediate representation of pipelines incorporating their micro-architecture optimizations. While LECA has previously developed formal models of pipelines for TA detection within code, these models were manually created.
• Utilizing the formally generated models as part of a pipeline analysis in a static WCET analysis tool provided by a collaborative partner. Specifically, the outcomes of cache analyses will guide the identification of temporal variations to be considered in the detection of TAs within basic blocks of input code.
• Defining microarchitectural-level instructions to alleviate the presence of various types of TAs at basic-block boundaries. These instructions will play a crucial role in the exploration process of RISC-V embedded microarchitectures, particularly when targeting safety-critical systems.
You are also expected to :
• Communicate about the work to the project partners, but also work directly with the French partners of the project;
• Participate in the scientific dissemination of the team's research results (contributions to publications in international conferences) and in the development of our innovations (writing of patents).
• To carry out your mission, you will benefit from a first class environment at CEA LIST with access to a large number of reference tools and a strong experience in the application of formal methods to the verification of properties such as temporal anomalies.
