This paper introduces a reflective functional reactive programming language designed for resource-constrained embedded systems. Using the reflection mechanism provided by the language, a program module can observe or modify its execution process via time-varying values that are connected to the internal of the metalevel of the module. Thus reflective operations are also reactive and described in a declarative manner. An example shows how the mechanism can realize an adaptive runtime that reduces the power consumption of a small robot.

Takuo Watanabe is Professor in the Department of Computer Science at Tokyo Institute of Technology. He received his Ph. D. from the Department of Information Science at the Tokyo Institute of Technology in 1991. He is working in the area of programming languages, programming methodologies, and formal methods. His research focuses on understanding the nature of reflective behaviors in concurrent systems, inventing new applications of computational reflection, and developing new abstraction mechanisms and programming models for safe/secure systems.
