Digital control theory is based on sampling intervals that have to be strictly met in order to get predictable behaviors. However, a real-time system may introduce execution jitters that may cause unpredictable effects on the control application. Stability, overshoot and settling time may be affected when an inadequate real-time system is used. Several papers have proposed different mechanisms to measure the jitter that a real time system produces. However, jitter can not be translated as a performance criterion in control theory. On the other hand, frequency domain techniques are widely applied in control theory for designing control strategies, as well as analyzing and measuring the performance of control mechanisms. In this paper, frequency domain analysis is used to measure the perturbations that a real-time operating system may produce on a control application. Harmonic distortion is defined as a criterion to evaluate the control performance of the the application. Experiments show that higher priority tasks are likely to be used for control tasks since the perturbation produced up to an utilization factor of 70% is adequate for most control applications.","PeriodicalId":267580,"journal":{"name":"2016 Seventh Argentine Conference on Embedded Systems (CASE)","volume":"186 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120971424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most efficient solution to this problem is to build a single in-vehicle network to support the delay and bandwidth constraints generated by each type of device. The main goal of this paper is to describe and analyse the performance of a deterministic network management module created to reduce jitter and packet loss, given variable traffic conditions. The most relevant parameters are obtained by simulation work, which permits to establish the actions and policies to execute the prototype modules for this kind of networks.","PeriodicalId":267580,"journal":{"name":"2016 Seventh Argentine Conference on Embedded Systems (CASE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127357236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach takes into account some typical features of this kind of systems, i.e. in a given state of a FSA, usually only a few among a large set of system inputs are taken into account. In addition to this, the system presents identical reaction to many inputs in several states. These and other considerations allow the proposal of a modeling strategy that belongs to the \"divide and conquer\" paradigm.","PeriodicalId":267580,"journal":{"name":"2016 Seventh Argentine Conference on Embedded Systems (CASE)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133126231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This highlights the need to understand the power consumption of the device in the early architectural phases of SoC design. The Power Analysis tooling, centered on Network on a chip, and developed as part of this project allows for quick iteration of power management topologies and tradeoffs in power management policies. The approach followed allows for successive iteration and composability of the solution as the design progresses and additional details become available. Flexibility is present in the system to assign both degree of uncertainty and replace the imprecise information with new information as the design process is completed.","PeriodicalId":267580,"journal":{"name":"2016 Seventh Argentine Conference on Embedded Systems (CASE)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115150963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
