A processing system to reduce energy consumption and improve performance in a processor, controlled by compiler inserted information ahead of a selected branch instruction, to statically expose and control how the prediction should be completed and which mechanism should be used to achieve energy and performance efficiency. The defibrillator is shaped and sized such as to be directly placeable on the patient’s chest. By mounting the window directly to the image sensor and the mount directly to the window, the substrate surface area of the optical module is minimized. If the client receives the control packet, the client performs a process according to the messages included in the control packet.
