Abstract: This paper presents a proposal for a new Ada profile targeted to microcontrollers with tight memory constraints. The profile has the same restrictions that the Ravenscar profile but includes a new scheduling policy based on the "one-shot task" model that allows stack sharing techniques to be applied to Ada tasks. A preliminary implementation based on a small kernel, a modified run-time system and an automatic code generation tool has been developed. The initial tests bring promising results, showing the profile is functionally correct and has a small memory footprint.
