# What is bidirectional shift register with parallel load?

## What is bidirectional shift register with parallel load?

A bidirectional shift register is capable of shifting in both the directions. The Universal shift register is a combination design of bidirectional shift register and a unidirectional shift register with parallel load provision. A n-bit universal shift register consists of n flip-flops and n 4×1 multiplexers.

What is a bidirectional shift register?

Bidirectional shift registers are the registers which are capable of shifting the data either right or left depending on the mode selected. If the mode selected is 1(high), the data will be shifted towards the right direction and if the mode selected is 0(low), the data will be shifted towards the left direction.

What is parallel load of a shift register?

Parallel load means to load all flip-flops of a register at one time. Serial load means to load the flip-flop of a register one bit at a time. The number of clock pulses required to shift all bits of a register completely in or completely out of the register is equal to the number of flip-flops in the register.

### Which register can perform shift right shift left and parallel loading?

Universal Shift Register A “Universal” shift register is a special type of register that can load the data in a parallel way and shift that data in both directions, i.e., right and left. The input M, i.e., the mode control input, is set to 1 to perform the parallel loading operation.

What is 4-bit bidirectional shift register?

4 –bit Bidirectional Shift Register: Bidirectional shift register allows shifting of data either to left or to the right side. It can be implemented using logic gates circuitry that enables the transfer of data from one stage to the next stage to the right or to the left, depend on the level of control line.

What is 4 bit bidirectional shift register?

## How a bidirectional shift register is converted in universal shift register?

When the mode pin is connected to GROUND, the universal shift register will operate/ behave as Bi directional shift register. To shift the data to right, the input is connected to the AND gate – 1 of the first flip flop; through serial input pin.

What is a shift register that will accept a parallel input or a bidirectional serial load and internal shift features?

A shift register that will accept a parallel input or a bidirectional serial load and internal shift features is called as? Explanation: A shift register can shift it’s data either left or right. The universal shift register is capable of shifting data left, right and parallel load capabilities.

What is meant by parallel load?

Correct Answer : Loading data in all four flip-flops at the same time.

### What are the different types of registers explain the parallel input serial output shift register?

There are four types of shift registers: serial in-serial out (SISO) shift registers, in which data is input serially until it reaches the output; serial in-parallel out (SIPO) shift registers, in which the data is input serially one bit at a time and output in a parallel form; parallel in-serial out (PISO) shift …

Which IC can be used as 4-bit bidirectional shift register?

74LS194 – 4-bit Bi-directional Shift Register IC.

Is bidirectional shift register and universal shift register same?

Unidirectional shift registers and bidirectional shift registers are combined together to get the design of the universal shift register. It is also known as a parallel-in-parallel-out shift register or shift register with the parallel load.

## Which IC can be used as 4 bit bidirectional shift register?

In what type of shift register do we have access to only the leftmost and rightmost flipflops?

The SISO shift register is one of the simplest of the four configurations as it has only three connections, the serial input (SI) which determines what enters the left hand flip-flop, the serial output (SO) which is taken from the output of the right hand flip-flop and the sequencing clock signal (Clk).

What are the different types of shift registers?

Following are the four types of shift registers based on applying inputs and accessing of outputs.

• Serial In − Serial Out shift register.
• Serial In − Parallel Out shift register.
• Parallel In − Serial Out shift register.
• Parallel In − Parallel Out shift register.

### What is meant by parallel loading the register single choice?

What is meant by parallel loading the resistor?

Resistors in parallel connection are connected to the same nodes from both ends. This can be identified by the presence of more than one way for the current to flow. The potential difference across the resistors is the same as that across the resistor which is equal to the supply potential.

What is 4-bit bidirectional shift register with parallel load?

A 4-bit bidirectional shift register with parallel load is shown in below Figure: Each stage consists of a D flip-flop and a 4 x 1 multiplexer. The two selection inputs 51 and 50 select one of the multiplexer data inputs for the D flip-flop.

## What is a parallel-in-parallel-out shift register?

The shift register allows parallel input (data is given separately to each flip flop and simultaneously) and produces a parallel output, known as the Parallel-In parallel-Out shift register. The logic circuit given below shows a parallel-in-parallel-out shift register. The circuit consists of four D flip-flops which are connected.

What is a serial in parallel out shift register?

Serial-In Parallel-Out shift Register (SIPO) The shift register, which allows serial input (one bit after the other through a single data line) and produces a parallel output, is known as the Serial-In Parallel-Out shift register. The logic circuit given below shows a serial-in-parallel-out shift register.

What is the difference between shift left and shift right registers?

The registers which will shift the bits to the left are called Shift left registers. The registers which will shift the bits to the right are called Shift right registers. Shift registers are basically of four types, such as:
