Abstract
An event trigger master coupled to a first peripheral device and including an event receiving interface, a storage element, a state machine, and a master interface is provided. The event receiving interface is configured to receive an event request. The storage element includes a command queue to store a set command. The state machine performs the set command to access the first peripheral device or a second peripheral device in response to the event request being triggered. The master interface is coupled to the state machine, the first peripheral device, and the second peripheral device. The state machine accesses the first or second peripheral device via the master interface.
Claims19
An event trigger master coupled to a first peripheral device, comprising:
- an event receiving interface configured to receive a first event request;
- a storage element comprising a first command queue to store a first set command;
- a state machine performing the first set command to access the first peripheral device or a second peripheral device in response to the first event request being triggered;
- and
- a master interface coupled to the state machine, the first peripheral device, and the second peripheral device,
- wherein the state machine accesses the first or second peripheral device via the master interface.
A control chip comprising:
- a first peripheral device;
- a second peripheral device;
- a peripheral system bus coupled to the first and second peripheral devices;
- and
- an event trigger master communicating with the first and second peripheral devices via the peripheral system bus and comprising:
- an event receiving interface configured to receive a first event request;
- a storage element comprising a first command queue to store a first set command;
- a state machine performing the first set command to access the first or second peripheral device in response to the first event request being triggered;
- and
- a master interface coupled between the state machine and the peripheral system bus,
- wherein the state machine accesses the first or second peripheral device via the master interface and the peripheral system bus.
The control chip as claimed in claim 14, wherein the event trigger master responds to the first event request which is triggered, and the processor does not respond to the first event request which is triggered.
A control method controlling a first peripheral device and a second peripheral device and comprising:
- storing a set command provided by a processor;
- determining whether an event request is triggered;
- and
- performing the set command to access the first or second peripheral device in response to the event request being triggered,
- wherein the set command is performed by an event trigger master, the event trigger master responds to the event request which is triggered, and the processor does not respond to the event request which is triggered.
