Question

Bidirectional shift register can be used to perform multiple operations. Design a 4-bit bidirectional shift register which performs shift up operation when all the selection input lines are having input zero.​

Answer 1

Answer:

The Shift Register is another type of sequential logic circuit that can be used for the storage or the transfer of binary data

Answer 2

Bidirectional shift register can be used to perform multiple operations. Design a 4-bit bidirectional shift register which performs shift up operation when all the selection input lines are having input zero.​

• Bidirectional shift registers are those that have the ability to shift both ways. The essential input and output terminals for parallel transfer are provided by some shift registers. All of the capabilities described below are included in even the most basic shift register.
• Depending on the mode used, bidirectional shift registers have the ability to move the data either right or left. The data will be shifted if the mode is 1 (high), which shifts it in the right direction, or 0 (low), which shifts it in the left direction.
• For each flip flop, data is provided independently and in the same manner, and each flip flop's output is also gathered separately. Similar to the SISO Shift register, a Parallel in Parallel out (PIPO) shift register serves as a delay element and is employed as a temporary storage device.
• shift register is employed as a parallel to serial converter to transform parallel data into serial data.
• The serial data is converted into parallel data using a shift register as a serial to parallel converter.
