Distributing power shared between an accelerated processing unit and a discrete graphics processing unit

A method by an apparatus, the method comprising:

• determining a first power provided to an integrated coprocessor comprising at least one central processing unit (CPU) core and at least one graphics processing unit (GPU) core, the integrated coprocessor being configured to generate commands for execution on a discrete coprocessor external to the integrated coprocessor;
• determining a second power provided to the discrete coprocessor;
• and
• modifying at least one of the first power or the second power based on characteristics of workloads executing on the integrated coprocessor and the discrete coprocessor, a reduced platform power limit that is lower than a platform limit shared by the integrated coprocessor and the discrete coprocessor, and at least one of:
• a power dissipation of at least one of a heat dissipation device coupled to the integrated coprocessor or a heat dissipation device coupled to the discrete coprocessor;
• or
• a skin temperature determined for an exterior portion of the apparatus configured for contact by a user, wherein the skin temperature is determined based on at least one of:
• temperature measurements taken by one or more sensors proximate to at least one of a casing or a display of the apparatus;
• or
• activity metrics associated with one or more components of the apparatus, wherein the activity metrics indicate an amount of heat generated by the one or more components.

An apparatus comprising:

• an integrated coprocessor comprising a central processing unit (CPU) and an integrated graphics processing unit (iGPU), wherein the CPU is configured to generate commands for execution on the iGPU and a discrete coprocessor;
• and
• power distribution circuitry configured to shift power dynamically between the integrated coprocessor and the discrete coprocessor based on a platform power limit that is shared by the integrated coprocessor and the discrete coprocessor and in response to changes in characteristics of workloads executing on the integrated coprocessor and the discrete coprocessor, wherein the power distribution circuitry is further configured to shift power dynamically between the integrated coprocessor and the discrete coprocessor based on at least:
• a power dissipation of at least one of a heat dissipation device coupled to the integrated coprocessor or a heat dissipation device coupled to the discrete coprocessor.
