Abstract
A method and module for programmable power management and a system on chip are disclosed. The module includes: a token ring and an operation unit. The token ring is provided with a cyclically running token and forming a clock information. The operation unit is configured to perform a corresponding power management operation according to a predetermined operation step register and the token; wherein the step register records a time sequence for performing power management operations, the time sequence being represented by the clock information.
Claims20
A module for programmable power management, comprising:
- a token ring, provided with a cyclically running token and forming a clock information;
- and
- an operation unit, configured to perform a corresponding power management operation according to a predetermined step register and the clock information;
- wherein the step register records a time sequence for performing power management operations, the time sequence being represented by the clock information.
A method for programmable power management, comprising:
- predetermining several step registers, each step register recording a time sequence for performing at least one power management operation;
- configuring a token ring, the token ring comprising a cyclically running token and forming a clock information, the time sequence being represented by the clock information;
- and
- performing a corresponding power management operation according to the token and the step register.
A chip for power management, comprising
- a token ring, provided with a cyclically running token and forming a clock information;
- and
- an operation unit, configured to perform a corresponding power management operation according to a predetermined step register and the clock information;
- wherein the step register records a time sequence for performing power management operations, the time sequence being represented by the clock information.
A system on chip, comprising a module for power management configured to perform switching between a dormant state and an operating state of the system on chip;
- the module comprising
- a token ring, provided with a cyclically running token and forming a clock information;
- and
- an operation unit, configured to perform a corresponding power management operation according to a predetermined step register and the token;
- wherein the step register records a time sequence for performing power management operations, the time sequence being represented by the clock information.
