1 INTRODUCTION
Many applications exist in which hard real­time transactions must be sup­
ported; examples include embedded control applications, defense systems, and
avionics systems. With the recent advent of workstation­class multiprocessor
systems, multiprocessor­based implementations of these systems are of growing
importance. Unfortunately, the problem of implementing hard real­time trans­
actions on multiprocessors has received relatively little attention. With most
(if not all) previously­proposed schemes for implementing such transactions,
the kind of transactions that can be supported is often limited, and worst­case
performance is often poor, adversely impacting schedulability.
We present here a new scheme for implementing hard real­time transactions on
multiprocessors that does not place undue restrictions on the kinds of transac­
