  Ne-XVP was a research project executed between 2006-2008 at NXP Semiconductors. The project undertook a holistic approach to define a next generation multimedia processing architecture for embedded MPSoCs that targets programmability, performance scalability, and silicon efficiency in an evolutionary way. The evolutionary way implies using existing processor cores such as NXP TriMedia as building blocks and supporting industry programming standards such as POSIX threads. Based on the technology-aware design space exploration, the project concluded that hardware accelerators facilitating task management and coherency coupled with right dimensioning of compute cores deliver good programmability, scalable performance and competitive silicon efficiency.
