A control circuit may be configured to control light emitting diode (LED) driver circuits. The control circuit may be configured to generate a multicast of pixel intensity values based on data in memory or data received from a data source, and output the multicast on an interface, which may comprise a one-wire uni-directional interface. In some examples, a plurality of drivers may receive the multicast, and each of the plurality of drivers may drive different sets of LEDs based on the multicast.

A context-based protection system uses tiered protection structures including master protection units, shared memory protection units, a peripheral protection units to provide security to bus transfer operations between central processing units (CPUs), memory array or portions of arrays, and peripherals.

Context-based protection system

A method of calibrating a module whose operation is dependent upon a module clock signal, the method comprising: over each calibration period of a plurality of such periods, obtaining a measure of the frequency of an observed signal, the observed signal being the module clock signal or a clock signal generated based upon the module clock signal; influencing operation of the module in dependence upon the obtained measures so as to calibrate the module; and for each said calibration period, taking account of a position in time of the end of that calibration period relative to a particular feature of the observed signal and delaying the start of the following calibration period relative to a subsequent said particular feature of the observed signal in dependence upon that position.
