Connecting Peripheral Interfaces to a Multithreaded Java Microcon- troller

We investigate the suitability of hardware multithreading for real-time event handling in combination with a Java microcontroller. Our aim is to design all hardware components such that the program execution time can be statically calculated in a cycle-accurate manner. In the field of microcontrollers it is important to incorporate peripheral interfaces into the processor die. We explored the special requirements and problems of connecting peripheral interfaces to a multithreaded processor core that simultaneously executes more than one thread in the processor pipeline. We present different solutions of the connection problem and discuss pros and cons with respect to real-time applications.
