A device for providing a security breach indicative audio alert. The device includes: a security monitor adapted to detect a security breach in device and a loudspeaker, the device wherein including a secure audio alert generating hardware, adapted to participate, in response to the detection of the security breach, in a generation of a security breach indicative audio alert. The secure audio alert generating hardware is connected to an audio mixer that is adapted to mix the security breach indicative audio alert signal with audio signals generated by a software controlled audio source to provide a mixed signal. The audio mixer is further adapted to provide the mixed signal to the loudspeaker that reproduces the mixed signal as sound.

An integrated circuit comprises a shared resource for providing data to a buffer. The buffer is coupled to a buffer level monitor and a filling circuit. An access-requesting circuit is coupled to the shared resource for receiving the data from the shared resource when the access-requesting circuit has access to the shared resource. An arbiter is coupled to the shared resource, the filling circuit, and the access-requesting circuit, for receiving access requests from the filling circuit and from the access-requesting circuit, and for granting to a selected one thereof access to the shared resource. A controller is coupled to the buffer level monitor and to the access-requesting circuit, for causing the access-requesting circuit to reduce a rate of access requests sent to the arbiter when a condition involving the monitored level of data in the buffer indicates an anticipated violation of a timing constraint.

A display controller for controlling data in an isochronous display where fluctuation of data feed latency occurs, the display controller including an input memory which receives pixel data and transmits the pixel data through a main route and a secondary route; wherein pixel data is transmitted through the main route and is processed for delivery to the display in a predetermined manner; characterized in that the secondary route comprises a memory for storing a two-dimensional section of the pixel data that corresponds at least in part to the pixel data being transmitted through the main route at that time; further characterized in that the display controller includes a detector for identifying a data feed latency event and in response there to switching the transmission of the pixel data to the secondary route and processing the pixel data through secondary route for delivery to the display such that when a data feed latency event occurs the stored two-dimensional section of the pixel data from the secondary route is displayed on the display.

Unified memory architecture and display controller to prevent data feed under-run

A method for controlling power consumption of a processor, the method includes: receiving an indicator that indicates that the processor is expected to change its activity; determining, in response to the indicator and to a current power consumption of the processor, whether to change a frequency of a clock signal that is provided to the processor; and changing, if determining to change the frequency of the clock signal, the frequency of the clock signal by a reduction of the frequency of the clock signal that is followed by an increment of the frequency of the clock signal; wherein the changing of the frequency of the clock signal is responsive to an expected change of a supply voltage that is supplied to the processor as a result of a possible change in a power consumption of the processor due to an expected change of activity of the processor.

Method for controlling a frequency of a clock signal to control power consumption and a device having power consumption capabilities

A system having memory access capabilities, the system includes: (i) a dynamic voltage and frequency scaling (DVFS) controller, adapted to determine a level of a voltage supply supplied to a first memory access requester and a frequency of a clock signal provided to the first memory access requester and to generate a DVFS indication that is indicative of the determination; (ii) a hardware access request determination module, adapted to determine a priority of memory access request issued by the first memory access requester in response to the DVFS indication; and (iii) a direct memory access arbitrator, adapted to arbitrate between memory access requests issued by the first memory access requester and another memory access requester in response to priorities associated with the memory access requests.
