Abstract
A data processing apparatus includes a plurality of power domains controlled by respective power control signals PCS. Power control circuitry includes mapping circuitry which maps a plurality of power status signals PSS indicative of the power status of respective power domains, and received from those power domains, to form the power control signals which are then supplied power domains. The mapping circuitry may be controlled by mapping parameters stored within a memory mapped array. The mapping parameters may specify that a given power control signal is either sensitive or insensitive to the power status of a particular other power domain within the data processing apparatus-2. The mapping parameters may be fixed or software programmable.
