WebA hardware timer is configured to create an interrupt every 1 ms. The ISR for that timer runs the scheduler, which chooses the task to run next. At each tick interrupt, the task with the highest priority is chosen to run. If the highest priority tasks have the same priority, they are executed in a round-robin fashion. http://faculty.cord.edu/kamel/08S-380/Presentations/Architectures.pdf cholesterol homeostasis definition
