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 ...

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.

Designed to execute instructions in a single clock cycle, the 8-bit MCU combines 13 interrupts with four priority levels, an 8-bit arithmetic logic unit, four 8-bit I/O ports, two timers, a ...

A computer is, at its core, just a bunch of transistors wired together. Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic ...

Most 8-bit microcontrollers can handle limited, multibyte operations such as addition and subtraction through the use of subroutines and the arithmetic unit's carry flag.
