An approach to satisfying the demand is to provide hardware support and leverage parallel computation. When providing hardware acceleration it is known that a custom specific circuit would provide a high performance solution. Providing a balance between delivering an application-specific circuit while achieving optimal utilization of a field programmable gate array is a difficult task.

We propose a method to build pipeline structures incrementally from a simple one (already verified) to a more complex one. Moreover, we show how each increment can be integrated in a CTL specification. We define increments to model treatment delay and treatment abortion of a pipeline flow, and we formalize the composition of the different increments. In order to represent the increments added to an architecture, we derive a set of CTL formulae transformations. Finally we model a control flow of a protocol converter by composition of these increments. We show how CTL properties of the complex architecture are built by applying automatic transformations on the set of CTL properties of the simplest architecture","PeriodicalId":113937,"journal":{"name":"Seventeenth IEEE International Workshop on Rapid System Prototyping (RSP'06)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122895553","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}

Each module is then mapped either to software or to hardware. The mapping process is driven by the hardware/software cost and performance parameters of each module. This makes hardware estimation important to evaluate the various candidate architectures. Lack of an efficient hardware estimation methodology and a supporting tool results in inefficient partitioning. In this paper, we present novel algorithms for clock period estimation and estimation of upper bound on execution time under given resource constraints which includes constraints on number of ports in the register file and memory.

However, with this increasing of the abstraction level, software engineers do not have an exact idea of the impact of their modeling decisions on important issues such as performance, energy, and memory footprint for a given platform. In our approach, analytical estimation of data and program memory, performance, and energy are obtained directly from UML models. Experimental results show a very small estimation error when software components are reused and their costs on the target platform are already known. Real-life applications are modeled in different ways and demonstrate the effectiveness of the estimates in an early design space exploration, allowing the designer to quickly compare different modeling solutions, with estimation errors as low as 5%","PeriodicalId":113937,"journal":{"name":"Seventeenth IEEE International Workshop on Rapid System Prototyping (RSP'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133661256","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}

Memory is becoming a key player for significant improvements in embedded systems (power, performance and area). With the emergence of more embedded multimedia applications in the industry, this issue becomes increasingly vital. These applications often use multi-dimensional arrays to store intermediate results during multimedia processing tasks. A couple of key optimization techniques exist and have been demonstrated on SoC architecture. This paper presents these techniques and their impact on a MPSoC environment and brings forward improvements. These techniques allow for optimization of memory space, reduction of the number of cache misses and extensive improvement of processing time extensively. In this paper's case study, theses techniques yield an average increase of the data cache hit rate by 20% and an average decrease of processing time by 50%","PeriodicalId":113937,"journal":{"name":"Seventeenth IEEE International Workshop on Rapid System Prototyping (RSP'06)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127287673","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}
