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 ...

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.

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.

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

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 ...

An earlier logic chip used as a building block for CPUs. Bit slice processors used arithmetic logic units (ALUs) that typically came in 4-bit increments, although 1- and 2-bit devices were also ...

The CPU and memory work together to process instructions and run programs. There are different types of memory – volatile and non-volatile. The Arithmetic and Logic Unit (ALU) is where the CPU ...
