## What is array multiplier in computer architecture?

An array multiplier is a digital combinational circuit used for multiplying two binary numbers by employing an array of full adders and half adders. This array is used for the nearly simultaneous addition of the various product terms involved.

**Why is Array multiplier a fast multiplier?**

Array multiplier is an efficient layout of a combinational multiplier. By employing array of full adders and half adders the multiplication of two binary numbers is carried out in the array multiplier. For the simultaneous addition of all the product terms the array is used in the multiplier [3]-[4].

**What is 4×4 array multiplier?**

A 4×4 bit Array multiplier is constructed as the basic building block for higher order multipliers. In Fig. 1 the sketch diagram of the multiplier and 4 bit array architecture is shown with two major blocks as AND gate logic and 1-bit full adder in Fig.

### What are the advantages of Array multiplier?

The advantages of array multiplier are,

- Minimum complexity.
- Easily scalable.
- Easily pipelined.
- Regular shape, easy to place and route.

**What is Braun array multiplier?**

Braun multiplier is a type of parallel array multiplier. The architecture of Braun multiplier mainly consists of some Carry Save Adders, array of AND gates and one Ripple Carry Adder.

**Which logic gate do we use while designing array multiplier?**

In the proposed array multiplier, the full adder cells and half adder cells are implementing by using double pass transistor logic (DPTL). The full adders and half adders are designed using inverter based four transistor XOR gate to reduce the power dissipation.

## What is multiplier model?

The basic idea behind the multiplier model is that—up to the limit set by “full employment” or potential GDP—the actual level of employment and output depends on the state of aggregate demand (AD).

**What are the three multipliers?**

Here we detail about the top three types of multipliers in economics.

- (a) Employment Multiplier:
- (b) Price Multiplier:
- (c) Consumption Multiplier:

**What are the uses of multiplier?**

Multiplier theory has taken investment as the important factor of the economy. The proportionate increase in the level of income and employment in the economy depends up on the multiplier. This clarifies that increase in income and employment is on the basis of increase in investment.
