Function Replacement of Hard Real-time Systems Using Partial Reconfiguration

چکیده
This paper describes a method of function replacement in hard real-time systems implemented with FPGAs using dynamic partial reconfiguration. Prefetching of functions is used to avoid violations of real time conditions in cases where reconfiguration time is large compared to sampling time. A finite state machine determined from the specification of the real-time system is used to control reconfiguration and prefetching. Implementations for a distributed finite state machine of each module and a distributed communication system that supports loading and activation of functions are presented.
