Embodiment Construction

[0013] According to one embodiment, the electronic system can be fully or partially integrated in one or more chips, in other words the circuit arrangement (for example on a chip card) has a plurality of functional units or components to be powered. These components may be, for example, computing units, memories, peripherals or communication interfaces. For example, all components are supplied with a clock signal by a central clock generator. The current absorption (and thus energy consumption) of these components depends here on the clock frequency. All components can be quiescent independently of each other, thus drawing no (or very little) current. If many of these components become active at the same time, for example after waking up from a standstill, the resulting change in current (without regulation) can be so large that energy supply components (such as voltage regulators) cannot If the adjustment is made in time, the voltage will be disturbed, which may lead to the...

Abstract

The invention relates to a circuit arrangement and a method for controlling the operation of a plurality of components to be powered of the circuit arrangement. The circuit arrangement has a plurality of components to be supplied, wherein each component to be supplied is designed to output a signal indicating a subsequent energy requirement of the component to be supplied, and the circuit arrangement has a control device which is designed to A value representing the subsequent energy demand of a plurality of components to be supplied is determined, it is determined whether the value satisfies a predetermined criterion, and the operation of the components to be supplied is controlled as a function of whether the value satisfies the specified criterion.

Description

technical field [0001] Embodiments generally relate to circuit arrangements and methods of controlling the operation of a plurality of components to be powered of a circuit arrangement. Background technique [0002] Simultaneous switching on of consumers in the chip (that is to say the components to be powered) can lead to malfunctions due to the resulting current changes, for example supply voltage disturbances and consequent functional failures. This can occur, for example, when many consumers are switched on at the same time, e.g. when several components to be powered are woken up from a standstill at the same time; the buffer capacity of the chip is relatively small, e.g. when using manufacturing processes that result in extremely small structures ; There are only few supply voltage connections, eg in the case of a chip card; the chip's internal voltage regulator cannot regulate the supply voltage quickly enough due to its current state. [0003] A more gradual increase...
