This paper describes new programming language primitives that are
designed to support statistical Quality of Service (QoS) guarantees 
and simple fault tolerance. We believe that such features would be useful
in the implementation of next generation mechatronic systems that combine
real time control applications and multimedia. The paper does not describe 
a complete programming language, but instead builds on top of the Real-Time 
Concurrent C (RTCC) language. Five new language constructs are introduced,
each for a specific purpose. These are: specification of statistical QoS
requirements, specification of complex value functions, synchronization of
periodic processes, barrier synchronization of periodic processes, and
simple fault tolerance via explicit task-processor binding. In each case
we provide a justification for incorporating the feature into RTCC. The
paper is intended as a presentation of our work in progress and discussion of
possible research directions.
