System and methods for controlling power delivery to system components are disclosed. A controller is communicatively coupled to a point-of-load converter through a first communication path and a shared memory is communicatively coupled to the point-of-load converter through a second communication path. A third communication path communicatively couples the controller and the shared memory. Control data is communicated from the controller to the point-of-load converter through the first communication path and measurement data is written from the point-of-load converter to the shared memory through the second communication path. The controller is operable to read the measurement data from the shared memory through the third communication path.
