ARITHMETIC LOGIC UNIT

Aim: The main aim of this project is to design an ALU system.

DESCRIPTION: 

In computing, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit (CPU) of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The processors found inside modern CPUs and graphics processing units (GPUs) accommodate very powerful and very complex ALUs; a single component may contain a number of ALUs.

ALUs can perform the following operations:

• Integer arithmetic operations (addition, subtraction, and sometimes multiplication and division, though this is more expensive)
• Bitwise logic operations (AND, NOT, OR, XOR)
• Bit-shifting operations (shifting or rotating a word by a specified number of bits to the left or right, with or without sign extension). Shifts can be interpreted as multiplications by 2 and divisions by 2.

REQUIRED COMPONENTS:

• FPGA
• XILINX ISE

REQUIRED SKILL SET:

• Knowledge on Digital design.
• Knowledge on VHDL programming.
