چکیده

In this paper we present example applications using a deadline instruction. The deadline instruction brings cycle accurate timing information into the application code. We have implemented the mechanism in a time-predictable Java chipmultiprocessor. As a proof of the accuracy that can be gained, a digital to analog conversion of audio signals is implemented completely in software. Furthermore, we show how the deadline instruction can be used to verify bytecode execution times on chip-multiprocessors and how to synchronize tasks to a timedivision based memory arbiter.
