gates in a single chip .
This is carried out (Designed) by Programming. Thus it is simple and easy to modify
the existing design (add more features) by changing the instructions alone in the
program and not the hardware. This final program is edited, compiled, synthesised and
using the proper device we s imulate a nd see the result ( working of the IC that we
have designed ) on the screen.
As we all know the importance of ALU in CPU, designing
Technology is a challenging task. the same using VLSI The arithmetic-logic unit performs arithmetic and logical operations on input data. This
section of the machine can be relatively small, consisting of as little as part of a
microprocessor chip. On the other hand, for large "number calculations," it can consist
of a considerable array of high-speed logic components. Despite the variations in size
and complexity, arithmetic and logical operations are always performed using the same
Although many functions can be performed by ALUs , the basic arithmetic operationsaddition, subtraction, multiplication, and d...
