This leads to limited programmability and restricted flexibility. With recent technological advances in high performance computing, scalable systems based on heterogeneous \"off the shelf\" modules are attractive as computing platforms in real-time embedded environments, leading to an emerging class of Scalable Heterogeneous High Performance Embedded (SHHiPE) systems. These systems offer advantages of low-cost, scalability, easy programmability, software portability, and the ability to incorporate evolving hardware technology. In order to satisfy the timing and predictability requirements that arise in embedded environments, several issues must be considered. These issues arise at the hardware level-such as choice of processing element architecture, and also at the software level-issues related to operating system and communication libraries. We propose an integrated methodology to develop efficient parallel solutions for signal processing applications on the SHHiPE platforms. Our approach is to develop scalable portable algorithms based on accurate computational models of the hardware platforms. We present preliminary performance results of such an approach applied to a radar signal processing problem.","PeriodicalId":111365,"journal":{"name":"Proceedings Second International Workshop on Real-Time Computing Systems and Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127936253","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}

For real-time applications, the allocation problem should directly address the issues of task and communication scheduling. In this context, the allocation of tasks has to fully utilize the available processors and the scheduling of tasks has to meet the specified timing constraints. Clearly, the execution of tasks under the allocation and schedule has to satisfy the precedence, resources, and other synchronization constraints among them. Recently, the timing requirements of the real-time systems emerge that the relative timing constraints are imposed on the consecutive executions of each task and the inter-task temporal relationships are specified across task periods. In this paper we consider the allocation and scheduling problem of the periodic tasks with such timing requirements. Given a set of periodic tasks, we consider the least common multiple (LCM) of the task periods. Each task is extended to several instances within the LCM. The scheduling window for each task instance is derived to satisfy the timing constraints. We develop a simulated annealing algorithm as the overall control algorithm. An example problem of the sanitized version of the Boeing 777 Aircraft Information Management System is solved by the algorithm. Experimental results show that the algorithm solves the problem in a reasonable time complexity.","PeriodicalId":111365,"journal":{"name":"Proceedings Second International Workshop on Real-Time Computing Systems and Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115665777","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}
