Abstract: In this paper we focus on the reduction of switching activity in combinational logic circuits. An algorithmic approach using k-map has been proposed which modifies the normal optimal solution obtained from k-map to reduce its switching activity. More than 10% reduction in switching activity has been observed using our method. The final solution(More)
In this paper we address the problem of minimization of power consumption in combinational circuits by minimizing the number of switching transitions at the output nodes of each gate. A powerful combinational logic optimization method using k-map is presented here that is based on disjoint implicants (implicates) of a function. More than 10% reduction in(More)
In this paper, we present a strongly fault-tolerant design for the k-ary n-cube multiprocessor and examine its reconfigurability. Our design augments the k-ary n-cube with ðjÞ n spare nodes. Each set of j regular nodes is connected to a spare node and the spare nodes are interconnected as either a ðkjÞ-ary n-cube if j 61⁄4 k2 or a hypercube of dimension n(More)
− This paper presents an efficient system level power saving method for DRAM with multiple power modes. The proposed method is based on the power aware scheduling algorithm that controls DRAM modules in coarse grain in which the scheduler assigns appropriate power modes to memory banks at context switching time. The method controls the transition of(More)
This paper examines the errors committed by human operators of large networks and systems. It proposes a formal procedure in which system defense mechanisms are used to improve the coordination between human operators and computer agents. Further, it discusses and compares the effectiveness of different types of system defense mechanisms by performing(More)
