An integrated circuit can include a processor system configured to execute program code. The processor system can be hard-wired and include a processor hardware resource. The IC also can include a programmable circuitry configurable to implement different physical circuits. The programmable circuitry can be coupled to the processor system. The programmable circuitry can be configurable to share usage of the processor hardware resource of the processor system. The processor system further can control aspects of the programmable circuitry such as power on and/or off and also configuration of the programmable circuitry to implement one or more different physical circuits therein.
