Method, Apparatus, and System for Energy Efficiency and Energy Conservation Including Power and Performance Balancing Between Multiple Processing Elements and/or a Communication Bus

A non-transitory medium including code, when executed, to cause a machine to perform the energy efficiency operations of:

• receiving a bus workload for a communication bus and a first processing element workload for a first processing element
• based on an integrated circuit including the communication bus and the first processing element reaching a limit;
• determining if the first processing element workload indicates the first processing element is a performance bottleneck;
• determining if a communication bus is able to accommodate the bus workload;
• capping a bus frequency of at least the communication bus in response to determining the first processing element workload indicates the first processing element is a performance bottle neck and determining the communication bus is able to accommodate the bus workload;
• and
• increasing a previous cap on bus frequency of at least the communication bus in response to determining the first processing element workload indicates the first processing element is a performance bottle neck and determining the communication bus is not able to accommodate the bus workload.

A method for efficient energy consumption comprising:

• determining a processing workload activity for a central processor on a package;
• determining a graphics workload activity for a graphics processor on the package;
• determining a bus workload activity for a communication bus on the package;
• determining if the package has reached a thermal or power limit;
• and
• in response to determining the package has reached the thermal or power limit, dynamically balancing power between the central processor, the graphics processor, and the communication bus based on at least the graphics workload activity and the bus workload activity.
