A logic circuit incorporating carry look-ahead in which efficiency can be achieved regarding the hardware for generating the sum signals and carry signals by a suitable choice of the adder gate, making use of the already present signal a.sub.1 .multidot.b.sub.i which is used for generating the carry look-ahead signal.

Logic full adder circuit

An integrated and programmable processor for word-wise digital signal processing. The processor has a multiplier element, an arithmetic and a logic unit, a data memory and a connection for a control memory which may be integrated on-chip. The elements are interconnected by means of a double bus on which addresses as well as data may be transported by means of suitable selectors. Consequently, a pipeline operation can take place within one instruction cycle.
