- Embedded microcontrollers are often programmed in plain C and lacksupport for multithreading and real-time scheduling. This can makeit very cumbersome to implement multirate feedback controlapplications. We have developed the TinyRealTime kernel forthe Atmel ATmega8L AVR to show that it is feasible to usehigh-precision, deadline-based scheduling even in a tiny 8-bitprocessor with 1 KB of RAM. The kernel is demonstrated in amultirate control application, where six periodic real-time tasks(four control tasks and two PWM tasks) are used to control twoball-and-beam processes.
