A register adequate for changing its binary data in one or both directions is known as a shift register. The logical design of a shift register includes a series of flip-flops, with the output of one flip-flop linked to the input of the next flip-flop.Operations of Shift RegisterThere are various ...

A register is a set of flip-flops with each flip-flop adequate for saving one bit of data. An n-bit register has a set of n flip-flops and is adequate for saving any binary data of n bits. In the flip-flops, a register can have combinational gates that implement specific data-processing ... Read More

The T flip-flop is also called toggle flip-flop. It is a change of the JK flip-flop. The T flip flop is received by relating both inputs of a JK flip-flop. The T flip-flop is received by relating the inputs ‘J’ and ‘K’. When T = 0, both AND gates are ... Read More

J-K flip-flop can be treated as an alteration of the S-R flip-flop. J represents SET, and 'K' represents CLEAR. In the JK flip-flop, the ‘S’ input is known as the ‘J’ input, and the ‘R’ input is known as the ‘K’ input. The output of the JK flip-flop does not ... Read More

Flip flops are an application of logic gates. A flip-flop circuit can stay in a binary state continually (as long as power is transferred to the circuit) before conducted by an input signal to switch states. S-R flip-flop represents SET-RESET flip-flops. The SET-RESET flip-flop includes two NOR gates and also ... Read More

The block diagram of an asynchronous communication interface is displayed in the figure. It works as both a sender and a receiver. The interface is boot up for a specific mode of transfer using a control byte that is loaded into its control register. The transmitter register receives a data ... Read More

A signed-magnitude method is used by computers to implement floating-point operations. Signed-2’s complement method is used by most computers for arithmetic operations executed on integers. In this approach, the leftmost bit in the number is used for signifying the sign; 0 indicates a positive integer, and 1 indicates a negative ... Read More

A scheduling system consists of program tasks, a target machine, and a schedule in which a specific performance criterion is optimized.Program Tasks − The characteristics of a parallel program can be defined as the system (T,

The general scheduling problem has been described in different ways in different fields. The classical problem of job sequencing in production management has influenced most of the solutions to this problem, which generally assumes a set of resources that could provide service to a set of consumers. The main objective ... Read More

There are two methods of cache-coherency which are as follows −Cache–Memory CoherenceIn a single cache system, coherence between memory and the cache is maintained using one of two policies − (1) write-through, and (2) write-back. When a task running on a processor P requests the data in memory location X, ... Read More
