| 发明名称 | Hierarchical power management circuit, power management method using the same, and system on chip including the hierarchical power management circuit | ||
| 摘要 | 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. | ||

| 主权项 | 1. 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 three, 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 and directly received by the i-th power management circuit from among the N power management circuits, wherein the first management circuit directly communicates with each of the remaining power management circuits among the N power management circuits. | ||
