Abstract: In an embodiment, the present invention includes a processor having a first domain with at least one core to execute instructions, a second domain coupled to the first domain and having at least one non-core circuit, and a power control unit (PCU) coupled to the first and second domains. The PCU may include a power sharing logic to receive encoded power consumption information from the second domain and to calculate an available power budget for the first domain based at least in part on the encoded power consumption information. Other embodiments are described and claimed.
