-Heterogeneous multi core processors can offer diverse computing capabilities. The efficiency of Market Basket Analysis Algorithm can be improved with heterogeneous multi core processors. Market basket analysis algorithm utilises apriori algorithm and is one of the popular data mining algorithms which can utilise Map/Reduce framework to perform analysis. The algorithm generates association rule...

noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. a common problem in imaging systems by using cmos or ccd sensors is appearance of  the salt and pepper noise. this paper presents cellular automata (ca) framework for noise removal of distorted image by the salt an...

Minimizing the response time to asynchronous events in a real-time system is an important factor in increasing the speed of response and an interesting concept in designing equipment fast enough for the most demanding applications. The present article will present the results regarding the validation of the nMPRA (Multi Pipeline Register Architecture) architecture using the FPGA Virtex-7 circui...

Parallel programming on multi-core processors has become the industry’s biggest software challenge. This paper proposes a novel parallel architecture for executing sequential programs using multi-core pipelining based on program slicing by a new memory/cache dynamic management technology. The new architecture is very suitable for processing large geospatial data in parallel without parallel pro...

ÐGiven a set of precedence constrained parallel tasks with their processor requirements and execution times, the problem of scheduling precedence constrained parallel tasks on multicomputers with contiguous processor allocation is to find a nonpreemptive schedule of the tasks on a multicomputer such that the schedule length is minimized. This scheduling problem is substantially more difficult t...

Contemporary multiprocessor real-time operating systems, such as VxWorks, LynxOS, QNX, and real-time variants of Linux, allow a process to have an arbitrary processor affinity, that is, a process may be pinned to an arbitrary subset of the processors in the system. Placing such a hard constraint on process migrations can help to improve cache performance of specific multi-threaded applications,...

A 2-dimensional Xover-based non-dominated sorting (2DXNS) genetic algorithm is proposed for multi-objective scheduling of static soft real-time tasks on heterogeneous computing systems. The objectives of scheduling problems are generally to minimize makespan, total processor idle time, and the number of processors as well as maximize guarantee ratio. In contrast to earlier approaches that commo...

This paper presents an implementation of Coincidence Algorithm on multi-core processors. The algorithm is suitable to solve combinatorial problems. The implementation uses Intel Threading Building Blocks library for parallel computation. The performance improvement is measured using several Traveling Salesman Problems. The result shows that a speedup of a dual-core processor over a single-core ...

A Web crawler is an important component of the Web search engine. It demands large amount of hardware resources (CPU and memory) to crawl data from the rapidly growing and changing Web. So that the crawling process should be a continuous process performed from time-to-time to maintain up-to-date crawled data. This paper develops and investigates the performance of a new approach to speed up the...
