We focus, in this paper, on multi-tasking, embedded control systems. Initially, system specification takes place at a high level of abstraction; detail is added in refinement steps as the development proceeds toward implementation. In previous work, we presented an approach for generating code, for concurrent programs, from Event-B. Translators generate program code for tasks that access data in a safe way, using shared objects. We did not distinguish between tasks of the environment and those of the controller. The work described in this paper offers improved modelling and code generation support, where we separate the environment from the controller. The events in the system can participate in actuating or sensing roles. In the resulting code, sensing and actuation can be simulated using a form of subroutine call; or additional information can be provided to allow a task to read/write directly from/to a specfied memory location. date: 2011-09 date_type: published event_title: SBMF2011 event_location: Sao Paulo, Brazil event_dates: Sept 2011 event_type: workshop refereed: TRUE related_url_url: http://eprints.ecs.soton.ac.uk/cgi/export/eprint/22771/Atom/ecs-eprint-22771.xml related_url_url: http://eprints.ecs.soton.ac.uk/id/eprint/22771 related_url_url: http://eprints.ecs.soton.ac.uk/id/eprint/22771/contents related_url_url: http://eprints.ecs.soton.ac.uk/id/eprint/22771/contents related_url_url: http://eprints.ecs.soton.ac.uk/id/eprint/22771 related_url_url: http://eprints.ecs.soton.ac.uk/id/eprint/22771 citation: Edmunds, Andrew and Rezazadeh, Abdolbaghi and Butler, Michael (2011) From Event-B Models to Code: Sensing, Actuating, and the Environment.
