The residue number system (RNS) has been an important research field in computer arithmetic for many decades, mainly because of its carry-free nature, which can provide high-performance computing architectures with superior delay specifications. Recently, research on RNS has found new directions that have resulted in the introduction of efficient algorithms and hardware implementations for RNS with...
Partially runtime reconfiguration is an efficient method for use in the limited resources in order to increase the performance of the system. In these systems, all the processes use the reconfigurable resources and place their hardware tasks at run time without affecting each other. One of the challenging problems in online task placement is fragmentation of reconfigurable resources. This paper focuses...
Frequent episode discovery in alerts generated by intrusion detection systems has useful information for administrators. In this paper we consider the process of discovering frequent episodes in event sequences. Counting the frequencies of a set of candidate episodes is the most computationally intensive part of this process. We investigate the frequency counting algorithms and present the hardware...
Partially runtime reconfiguration allows runtime mapping and execution of several tasks on a FPGA. In order to enhance the efficiency of the reconfigurable computing, multitasking on FPGAs is proposed. One of the challenging problems in multitasking systems is online task placement. This paper focuses on task placement in a reconfigurable system. Several techniques for nonrectangular tasks are investigated...
