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 ...

a, Schematic of a two-bit arithmetic unit, comprising six individual arithmetic logic units (ALU) as shown in Fig. 3b. b, Measured and expected output waveforms testing all possible input ...

We see a lot of discrete-logic computer builds these days, and we love them all. But after a while, they kind of all blend in with each other. So what’s the discrete logic aficionado to do if… ...

A single device can perform multiple logic operations.Last year, however, researchers showed that phase change memory could also be used to create logic gates, the basic functional units of a ...

When the industry was able to put the computer CPU on a single chip, it was called a microprocessor. CPUs consist of a processing unit called an ALU (arithmetic/logic unit), a control unit that ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device.
