Description
The DrTEE project is concerned with Distributed Real-Time
Execution Environments and in particular with those
applications which are implemented using the Ada 95
programming language. The project has involved the design
and implementation of a testbed intended to support
experiments in kernel design, architecture design and the
practical application of our feasibility analysis.
The testbed takes the form of a number of nodes each
comprising a Single Board Computer (SBC) built around the
Motorola MC68376 micro controller. Communication between
nodes is achieved using the Controller Area Network (CAN)
protocol which provides prioritised and deterministic
communications facilities.In order to allow experimentation involving Ada 95
applications, the Gnat Ada 95 compiler had been ported to
the hardware platform used in the testbed. This porting
process has required the development of a predictable and
bounded kernel which provides the run-time support
required by Gnat. The kernel also provides a high level
interface to the CAN communication system. This interface
utilises the low level CAN communications facilities to
provide provide a deterministic, prioritised
communication system which allows arbitrary message
lengths and node and task level message addressing.Publications
