Abstract
A hierarchical power management circuit includes N power management circuits respectively included in N power domains each including at least one intellectual property (IP), wherein N is a natural number greater than one. The i-th (1<i<N) power management circuit from among the N power management circuits manages supply of power to an (i+1)th power domain from among the N power domains in response to a power management request signal output from a first power management circuit from among the N power management circuits
Claims17
A hierarchical power management circuit, comprising:
- N power management circuits respectively included in N power domains each comprising at least one intellectual property (IP), wherein N is a natural number greater than one,
- wherein an i-th (1<i<N) power management circuit from among the N power management circuits manages supply of power to an (i+1)th power domain from among the N power domains in response to a power management request signal output from a first power management circuit from among the N power management circuits.
-8. (canceled)
A system on chip (SoC) comprising:
- N power domains each comprising at least one IP, wherein N is a natural number greater than one;
- and
- N power management circuits included in the N power domains, respectively,
- wherein an i-th (1<i<N) power management circuit from among the N power management circuits manages supply of power to an (i+1)th power domain from among the N power domains in response to a power management request signal output from a first power management circuit from among the N power management circuits.
A hierarchical power management circuit, comprising:
- N power management circuits respectively included in N power domains each comprising at least one intellectual property (IP), wherein N is a natural number greater than one,
- wherein an i-th (1<i<N) power management circuit from among the N power management circuits manages an operation of the at least one IP included in an (i+1)th power domain from among the N power domains in response to an operation management request signal output from a first power management circuit from among the N power management circuits.
