Reconfigurable system-on-chip (SoC) platforms arenow a physical reality. This gives a system substratewhich, physically at least, is fairly neutral with respect touse models and system architectures. When embeddedprocessors are present, the most obvious use model tofollow is to consider the system on chip as a scaled-downversion of a system on board: we call this a processor-centricmodel. To provide better access to many of thebenefits of the new SoC devices, we introduce analternative logic-centric model, where the environment ofa system is the driving force behind its architecture. Inparticular, the role of embedded processors is to assistthe majority processing being carried out in logic and ininput/output interfaces. We see such eccentric'architectures as the norm for the future, particularlygiven the vision of the disappearing computer' and therise of ambient intelligence'. We illustrate the generaldiscussion with examples drawn from our currentresearch into systems designed for message processing.
