Abstract
A method of reading data in an electronic system includes detecting whether a trigger signal in the electronic system is enabled, the trigger signal being selectively enabled according to at least one operating condition of the electronic system, as a consequence of detecting that the trigger signal is enabled, changing a size of read-ahead data based on the enabled trigger signal, and performing a read operation based on a read command and the changed size of the read-ahead data.
Claims20
A method of reading data in an electronic system, comprising:
- detecting whether a trigger signal in the electronic system is enabled, the trigger signal being selectively enabled according to at least one operating condition of the electronic system;
- as a consequence of detecting that the trigger signal is enabled, changing a size of read-ahead data based on the enabled trigger signal;
- and
- performing a read operation based on a read command and the changed size of the read-ahead data,
- wherein the trigger signal is indicative of whether the electronic system is connected to an external device.
2 more elements
An electronic system, comprising:
- an application processor configured to
- execute an operating system (OS) of the electronic system,
- detect a state of a trigger signal in the electronic system,
- change a size of read-ahead data based on the detected state of the trigger signal, and
- perform a read operation in the electronic system based on a read command and the changed size of the read-ahead data,
- wherein the trigger signal is selectively enabled according to an operating condition of the electronic system, and the size of the read-ahead data indicates an amount of data prefetched before the read operation is required in the electronic system;
- and
- a memory device configured to store the OS,
- wherein the state of the trigger signal indicates whether a predetermined application or process is to be executed by the electronic system.
