Even with dedicated compute cores, you need > cache coherency. One thing that we plan to push later is an XIP model where cores can share a single kernel text image but run with their own copies of data. So you end up with something like a loosely coupled multiprocessor system with some hardware support for multicore communication and peripheral sharing. --Mark -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
