摘要： An apparatus for calculating a representation of a result operand of the non-linear logical operation between a first operand and a second operand includes a first logic gate and a second logic gate. Each operand is represented by two auxiliary operands, which, when linearly combined together result in the respective operand. The first and second logic gates are designed such that an average energy consumption of the first or second logic gate is substantially equal to a plurality of combinations of auxiliary operands at the beginning of a first operation cycle and auxiliary operands at the beginning of a second operating cycle, the average energy being derivable from a plurality of different orders of occurrences of the first to fourth auxiliary operands.

Each feedback shift register includes a register input and a register output. The random bit stream generator further includes a Boolean output function configured to receive the plurality of register outputs from the plurality of feedback registers, to perform a first Boolean combination of the plurality of register outputs, and to provide a corresponding output bit, wherein a plurality of successive output bits forms a random bit stream. A feedback loop is configured to perform a second Boolean combination of the output bit with at least one register feedback bit of at least one of the feedback shift registers, so that the register input of the at least one feedback shift register is a function of the output bit.

摘要： A communication apparatus for communication according to a master-slave communication protocol is formed as a slave instance communicating with a master instance via a bus. The master instance is operative to switch the bus into a bus suspend state if no bus activity is present during a predetermined interval. In response to a bus suspend state, the slave instance makes a transition to a slave suspend state. The communication apparatus includes a monitor configured to monitor the bus activity and a transmitter configured to transmit a signal via the bus if the monitor does not recognize any bus activity during part of the predetermined interval and a transition of the slave instance to the slave suspend state is undesirable, wherein the signal is operative to prevent the master instance from switching the bus into the bus suspend state.
