 Digital Systems course archive of the University of Oxford

The archived course record links the teaching site spivey.oriel.ox.ac.uk/corner/Digital_Systems, whose current process/message-based system material is at spivey.oriel.ox.ac.uk/corner/Micro:bian_(Digital_Systems). The latter is later documentation and does not establish an identical API for the Phōs release named in the held 2019 examination. The solutions specify the request, interrupt and reply contracts explicitly rather than claiming such a binding.

The 3 September 2019 resit paper names Phōs in question 2 and describes a sensor-driver process serving concurrent clients. Public archive: Oxford examination archive, member 2018/L/a10101w1.pdf; the cover dates the paper despite its archive directory. This establishes the teaching context and process-based device-service example without specifying an implementation API.
