Abstract
The goal of the Rialto project at Microsoft Research is to build a system architecture supporting
coexisting independent real-time (and non-real-time) programs. Unlike traditional embeddedsystems real-time environments, where timing and resource analysis among competing tasks can
be done off-line, it is our goal to allow multiple independently authored real-time applications
with varying timing and resource requirements to dynamically coexist and cooperate to share the
limited physical resources available to them, as well as also coexisting with non-real-time
applications. This paper gives an overview of the Rialto real-time architecture as it is
implemented today and reports on some of the early results obtained. In particular, it describes
the use of time constraints, activities, CPU and other resource reservation, and the system
resource planner, and how they work together to achieve our goal of providing a flexible,
dynamic real-time computing environment.
