Conclusions: Arithmetic Logic Unit (ALU) for the Programmable Logic Device (RPLD) has been presented in this letter in a reversible way. The reversible version ALU aims at eliminating the energy ...

It is based on the Motorola MC14500 1-bit industrial controller, but since [David] changed the basic logic unit into an arithmetic-logic unit, he’s dubbing it the UE14500.

Since arithmetic and logic operations within processing ICs are a crucial factors for speed, we developed a new approach to the ALU.

In a video that has now amassed over 112,000 views, Kyle, known online as Shadowman39, debuted the Arithmetic and Logic Unit, ...

The Arithmetic and Logic Unit (ALU) is where the CPU performs the arithmetic and logic operations. Data is passed to the ALU to allow the required calculations to be carried out.

Perhaps this CPU-less computer with a single NOR-gate instead of an arithmetic-logic unit is enough of a hacker flex? We certainly think so.
