As an important aspect of the hardware resource consolidation in virtualization environment, memory consolidation and over-commitment has been motivated by the increasing elastic computing cloud platform. The most popular consolidation technology, Memory Balloon, might introduce serious performance penalty with thrashing when guest memory usage changes dramatically. In order to overcome the drawback...
PTL (projection temporal logic) is a kind of temporal logic which can handle both sequential and parallel computation. In this paper, we proposed a formal approach of specification and verification of SOC using PTL. With this approach, PTL is used in high level design and hardware/software co-design for the formal specification and verification of a SOC system or its hardware/software parts. A simple...
