COMe-bIP2 / Features and Interfaces
4.14 VID-x
The processor implements the VID-x feature for improved control of core voltage levels when the processor enters a
reduced power consumption state. VID-x applies only when the processor is in the Intel Dynamic Acceleration Technology
performance state and one or more cores are in low-power state (i.e., CC3/CC4/CC6). VID-x provides the ability for the
processor to request core voltage level reductions greater than one VID tick. The amount of VID tick reduction is fixed and
only occurs while the processor is in Intel Dynamic Acceleration Technology mode. This improved voltage regulator
efficiency during periods of reduced power consumption allows for leakage current reduction which results in platform
power savings and extended battery life.
When in Intel Dynamic Acceleration Technology mode, it is possible for both cores to be active under certain internal
conditions. In such a scenario the processor may draw an Instantaneous current (ICC_CORE_INST) for a short duration of
tINST; however, the average ICC current will be lesser than or equal to ICCDES current specification.
