Informledge System (ILS) is a knowledge network with autonomous nodes and intelligent links that integrate and structure the pieces of knowledge. In this paper, we put forward the strategies for knowledge embedding and retrieval in an ILS. ILS is a powerful knowledge network system dealing with logical storage and connectivity of information units to form knowledge using autonomous nodes and mu...

In this paper we examine the performance of two multi-lateral cache schemes; one makes block allocation decisions correlated to the reference behavior of regions of memory (NTS), the other correlated to the reference behavior of memory accessing instructions (PCS). To determine the efficacy of exploiting these reference correlation schemes to improve cache management, we compare the performance...
