Abstract: The technology disclosed herein determining one or more vulnerable instructions in workload code and determining one or more additional instructions to be inserted in the workload code based at least in part on a power model of a system bus of a processor, when a power model of a processor is dependent on an order of instructions of workload code, inserting the one or more additional instructions with dependency to the workload code to produce complementary power consumption of the system bus to power consumption of the system bus from executing the one or more vulnerable instructions; and when the power model is not dependent on the order of instructions of workload code, inserting the one or more additional instructions without dependency to the workload code to produce complementary power consumption of the system bus to power consumption of the system bus from executing the one or more vulnerable instructions.

Abstract: In one embodiment, a processor comprises a plurality of cores and a controller. Each of the plurality of cores may include: an execution circuit, a power measurement circuit to measure power consumption of the core and a first register to store a power-related context identifier to identify a process to be executed on the core. The controller may include: a plurality of energy status registers each associated with a power-related context identifier and to store energy consumption information of a process; and a control circuit coupled to the plurality of energy status registers, where the control circuit is to enable each of a plurality of processes to independently monitor the energy consumption information of the process and prevent each of the plurality of processes from monitoring the energy consumption information of other ones of the plurality of processes. Other embodiments are described and claimed.
