Abstract: Methods and apparatus employ a plurality of heterogeneous compute units and a plurality of non-compute units operatively coupled to the plurality of compute units. Power management logic (PML) determines a memory bandwidth level associated with a respective workload running on each of a plurality of heterogeneous compute units on an integrated circuit (IC), and adjusts a power level of at least one non-compute unit of a memory system on the IC from a first power level to a second power level, based on the determined memory bandwidth levels. Memory access latency is also taken into account in some examples to adjust a power level of non-compute units.
