This paper introduces the Irregular Stream Buffer (ISB), a prefetcher that targets irregular sequences of temporally correlated memory references. The key idea is to use an extra level of indirection to translate arbitrary pairs of correlated physical addresses into consecutive addresses in a new <i>structural address space</i>, which is visible only to the(More)
Belady's algorithm is optimal but infeasible because it requires knowledge of the future. This paper explains how a cache replacement algorithm can nonetheless learn from Belady's algorithm by applying it to past cache accesses to inform future cache replacement decisions. We show that the implementation is surprisingly efficient, as we introduce a new(More)
A decade since the availability of Mycobacterium tuberculosis (Mtb) genome sequence, no promising drug has seen the light of the day. This not only indicates the challenges in discovering new drugs but also suggests a gap in our current understanding of Mtb biology. We attempt to bridge this gap by carrying out extensive re-annotation and constructing a(More)
—The proposed system highlights a novel approach for creating a secure steganographic method and visual cryptography for data hiding in computer forensics. Although there has been an extensive research work in the past, but majority of the research work has no much optimal consideration for robust security towards the encrypted image. The proposed method(More)

— A Wireless Mobile Ad-hoc Network consists of a number of mobile nodes that temporally form a dynamic infrastructure less network. To enable communication between nodes that do not have direct radio contact, each node must function as a wireless router and potential forward data traffic of behalf of the other. Detecting malicious nodes (Attacker) in an(More)
This paper compares the performance of various filters on the images degraded by the fog. Denoising is vital for the image enhancement. It is difficult to remove the noise from the images while preserving the information and the quality of the image. For analysis filters like Median, Alpha Trim, Lee, Wiener, Anisotropic Diffusion and Guided filter are used.(More)
