System, apparatus and method for dynamically controlling current consumption of processing circuits of a processor

A system comprising:

• a system on chip (SoC) comprising:
• a plurality of cores and at least one graphics processor, each of the plurality of cores and the at least one graphics processor including a configuration register to store a dynamic current budget;
• and
• a power controller coupled to the plurality of cores and the at least one graphics processor, the power controller comprising an interface to receive current throttling hint information regarding a workload to be executed on the SoC from a software entity, the power controller further comprising a dynamic current sharing control circuit to generate the dynamic current budget for the plurality of cores and the at least one graphics processor based at least in part on the current throttling hint information, wherein, for a first workload, the dynamic current sharing control circuit is to:
• set the dynamic current budget for at least one of the plurality of cores to a configured maximum current budget for the at least one core;
• and
• set the dynamic current budget for the at least one graphics processor to less than a configured maximum current budget for the at least one graphics processor;
• and
• a dynamic random access memory coupled to the SoC.
