This paper describes how a dedicated Time Management Unit (TMU) is used to reduce the overhead of execution time control. While the implementation described here is for Ada 2012 and a GNAT bare-board run-time environment, the principles should be applicable to other languages and run-time systems. The TMU has been implemented as a peripheral unit for the Atmel AVR®32 UC3 series of microcontrollers, and test results from simulation with the syntheziable RTL code of this system-on-chip are presented.
