Abstract
Embodiments of the present disclosure relate to a system, a controller, and a method for operating the same. The amount of current that each of multiple power domain modules can use may be determined, and information regarding the amount of usable current may be indicated to each power domain module, thereby controlling the total sum of peak power used by the multiple power domain modules at a specific timepoint to be equal to or lower than a configured value.
Claims14
A system comprising:
- multiple power domain modules configured to respectively receive power supplied from different power sources;
- and
- a controller configured to control the multiple power domain modules, wherein
- the controller is configured to determine the amount of current that each power domain module can use and to indicate information regarding the amount of usable current to each power domain module, thereby controlling the total sum of peak power used by the multiple power domain modules,
- wherein the controller is configured to output at least one class signal to each power domain module, and each of the at least one class signal indicates whether or not each power domain module can use as much current as the amount of current configured in each class signal.
A controller configured to determine the amount of current that each of multiple power domain modules receiving power from different power sources, respectively, can use and to indicate information regarding the amount of usable current to each power domain module, thereby controlling the total sum of peak power used by the multiple power domain modules,
- wherein the controller is configured to output at least one class signal to each power domain module, and each of the at least one class signal indicates whether or not each power domain module can use as much current as the amount of current configured in each class signal.
A method for operating a system, the method comprising:
- determining the amount of current that each of multiple power domains modules receiving power from different power sources, respectively, can use;
- and
- indicating information regarding the amount of usable current to each power domain module,
- wherein, indicating information regarding the amount of usable current to each power domain module comprises:
- outputting at least one class signal to each power domain module, wherein each of the at least one class signal indicates whether or not each power domain module can use as much current as the amount of current configured in each class signal.
