This example shows how models of memory mapped I/O devices can be connected to the current version of Anthony's ARM model. The idea is to take the ARM next-state function and build a wrapper around it. The wrapper essentially models the effect of the environment, i.e. the I/O devices, as a relational operational semantics. This example is based on polling, but interrupt-driven I/O devices should also fit into the same wrapper-based approach.
