Abstract
We present an integrated framework for developing real­
time systems in which lock­free algorithms are employed to
implement shared objects. There are two key objectives of
our work. The first is to enable functionality for object shar­
ing in lock­free real­time systems that is comparable to that
in lock­based systems. Our main contribution toward this
objective is an efficient approach for implementing multi­
object lock­free operations and transactions. A second key
objective of our work is to improve upon previously proposed
scheduling conditions for tasks that share lock­free objects.
When developing such conditions, the key issue is to bound
the cost of operation ``interferences''. We present a general
approach for doing this, based on linear programming.
