DATA PROCESSING UNIT, MICROPROCESSOR, AND METHOD FOR PERFORMING AN INSTRUCTION

The present invention relates to a data processing unit for executing instructions stored in a memory comprising a plurality of registers coupled with an execution unit comprising a logic unit for execution of logic operations. The logic unit comprises a first logic operator which can be coupled with a first and second register as an input register and which generates an output bit as a result of a logic operation. It further comprises a Boolean operator which receives the output bit of the first logic operator as a first input and second input bit from a third register which generates an output bit as a result of a Boolean operation.
