The XMOS Architecture and XS1 Chips
David L. May · IEEE Micro · 2012
The XMOS architecture scales from real-time systems with a single multithreaded processor to systems with thousands of processors. Concurrent processing, communications, and I/O are supported by the instruction set of the XCORE processors and by the message-routing techniques and protocols in the XMOS interconnect. The event-driven architecture supports energy-efficient multicore and multichip systems in which cores are active only when needed.
