So what’s the discrete logic aficionado to do if they want to stand out from the pack? Perhaps this CPU-less computer with a single NOR-gate instead of an arithmetic-logic unit is enough of a ...

but with modern 74LVC gates laid out as they would be in the circuit diagram of the chip, and LEDs to show logic state at the different parts of the circuit. Thus when it is used to teach ALU ...

An Arithmetic and Logic Unit (ALU) is a digital circuit that performs arithmetic and logic operations. In this work, the demand is to design an 8-bit ALU and perform analysis at gate and layout ...

Logic gates are constructed on individual carbon nanotubes ... The realisation of these circuits is sufficient for the construction of a nano-ALU.
