Methods and apparatus employ a plurality of heterogeneous computing units and a plurality of non-computing units operatively coupled to the plurality of computing units. A power management logic (PML) determines a memory bandwidth level associated with a respective workload running on each of a plurality of heterogeneous computing units on the IC, and adjusting 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 level. Memory access latency is also considered in some examples to adjust power levels of non-compute units. 方法和装置采用多个异构计算单元和操作地联接到该多个计算单元的多个非计算单元。功率管理逻辑(PML)确定与在IC上的多个异构计算单元中的每个异构计算单元上运行的相应工作负载相关联的存储器带宽水平，以及基于所确定的存储器带宽水平来将该IC上的存储器系统的至少一个非计算单元的功率水平从第一功率水平调整到第二功率水平。在一些示例中还考虑了存储器访问时延以调整非计算单元的功率水平。
