The paper "Finding Response Times in a Real-Time System" by M. Joseph and P. Pandya addresses two major performance issues in real-time systems: ensuring the system can handle peak processing load without losing any inputs, and determining the response time for each device. The authors define a condition for handling peak load and describe methods to find exact worst-case response times. They also discuss the use of buffers to manage inputs and the potential benefits of multiple processors in real-time applications. The paper includes definitions, theorems, and examples to illustrate the concepts and provide practical solutions. The analysis is based on simple reasoning using interval arithmetic, making it widely applicable and extendable to handle problems like buffering. The authors conclude by emphasizing the importance of precise timing bounds in real-time systems and suggesting that automated analysis could be integrated into real-time programming languages.The paper "Finding Response Times in a Real-Time System" by M.
