Abstract
Sophisticated and flexible real-time systems will often use several versions of a program fragment that performs a particular action. These versions will differ only in their performance parameters, such as the time required, the resources consumed, and the precision of the results. This paper presents a theory of performance polymorphism, whereby the process of selecting a version from the available set is incorporated into the class hierarchy. The binding problem for this new style of polymorphism is discussed, and an equivalent problem of program flow analysis is described. The requirements for a simple implementation of performance polymorphism are presented.
