Working Principle of Bidirectional Shift Register
The bidirectional shift register operates based on clock pulses and control signals. It has two modes of operation: shift right and shift left. Let’s explore these modes in detail:
- Shift Right: In the shift right mode, the data is shifted from the leftmost bit to the rightmost bit. Each clock pulse triggers the transfer of data to the adjacent flip-flop on the right. The rightmost bit receives the input data, while the leftmost bit is discarded.
- Shift Left: In the shift left mode, the data is shifted from the rightmost bit to the leftmost bit. Each clock pulse triggers the transfer of data to the adjacent flip-flop on the left. The leftmost bit receives the input data, while the rightmost bit is discarded.
Bidirectional shift registers often have additional control inputs for shifting operations, such as parallel load, asynchronous clear, and synchronous clear. These inputs enable various functionalities, such as loading data into the register, clearing the register, and synchronizing the register with external events.
Bidirectional Shift Register
In the field of digital electronics and computer science, shift registers play a vital role in storing and manipulating data. Among the different types of shift registers, the bidirectional shift register holds a prominent position. This article aims to provide a comprehensive understanding of bidirectional shift registers, including their structure, working principle, and applications.
