Abstract: A method may include obtaining, by a host device, multiple interrupts from a data transform accelerator. The method may also include determining, by the host device, a first interrupt rate and a second interrupt rate. The method may further include determining, by the host device, an interrupt ratio based on the first interrupt rate relative to the second interrupt rate. The method may also include comparing the interrupt ratio to an interrupt threshold. The method may further include directing, by the host device, the data transform accelerator to adjust an interrupt throttle value associated with the multiple interrupts. The adjusting of the interrupt throttle value may be in response to the interrupt ratio satisfying the interrupt threshold.

Abstract: The invention refers to a method for indicating the current status of a removable media device provided for being loaded with at least one removable medium, and being connected to a device reading and/or writing AV storage media. The method has the steps of checking the type of user input upon occurrence of user input, keeping the status of the removable media device if the type of user input is not related to the removable media device, else checking whether a characteristic feature of the at least one removable medium has changed, keeping the current status if the characteristic feature of the at least one removable medium has not changed, and else updating the status.
