A previous study [1] demonstrates the advantages of replacing registers by FPGA embedded memories during the storage allocation phase of High-Level Synthesis. The trend in new FPGAs to have large amounts of onchip embedded memories motivated this proposition and resulted in substantial area decrease in the synthesized designs. This paper elaborates further on the various possibilities involved ...

Manycore processor systems are likely to be the future system structure, and even within range for usage in desktop or mobile systems. Up to now, manycore processors like Intel SCC, Tilera TILE or KALRAY’s MPPA are primarily intended to use for high performance applications, utilizing several cores with direct inter-core communication to avoid access to external memory. The spreading of these m...

In this paper, we describe how the mapping of virtual to physical memory that is set up by the operating system can have a significant and unexpected impact on the performance of STREAM [6] and a sparse solver “mini-application” that exhibits STREAM-like behavior. The Cray Performance Analysis Toolkit (CrayPAT) [2] is utilized to identify the cause of the performance degradation to be row buffe...

bandar abbas (center of hormozgan province) is the most important port city in the south of iran because of its historical places, cultural, economic, social and political importance. high risk of earthquake occurrence in this city and its province indicates the necessity of surveying the seismic vulnerability of buildings. the object of this paper is collected from existing buildings, compiled...

Data intensive service functions such as memory allocation/de-allocation, data prefetching, and data relocation can pollute processor cache in conventional systems since the same CPU (using the same cache) executes both application code and system services. In this paper we show the improvements in cache performance that can result from the elimination of the cache pollution using separate cach...

Oracle RDBMS has supported XML data management for more than six years since version 9i. Prior to 11g, textcentric XML documents can be stored as-is in a CLOB column and schema-based data-centric documents can be shredded and stored in object-relational (OR) tables mapped from their XML Schema. However, both storage formats have intrinsic limitations—XML/CLOB has unacceptable query and update p...

In the past, Symbolic Trajectory Evaluation (STE) has been shown to be effective for verifying individual array blocks. However, when applying STE to verify multiple array blocks together as a single system, the run-time OBDD sizes would often blow up. In this paper, we propose the use of both ATPG-based justification engine and symbolic simulation to facilitate the application of STE proof met...

The most popular adaptive dictionary coding scheme used for text compression is the LZW algorithm [2]. In the LZW algorithm, a changing dictionary contains common strings that have been encountered so far in t,he text. The dictionary can be represented by a dynamic trie. The input text is examined character by character and the longest substring (called a prefix string) of the text which alread...

Conventional object-oriented programming systems allow application programmers to structure each application as a set of objects. They do not allow longterm storage of the objects, nor do they allow sharing and concurrency within the object spaces. Persistent object systems and object-oriented databases have been developed to address some of these shortcomings. Persistent object systems provide...
