A control memory is a part of the control unit. Any computer that involves microprogrammed control consists of two memories. They are the main memory and the control memory. Programs are usually stored in the main memory by the users. Whenever the programs change, the data is also modified in ... Read More

A control unit drives the corresponding processing hardware by generating a set of signals that are in sync with the master clock. The two major operations performed by the control unit are instruction interpretation and instruction sequencing.The control unit is a part of the Central Processing Unit (CPU). The CPU ...

A bus is a structure that handles the data transmission in a computer system or network. The common bus of 16-bit is controlled by the selection inputs S2, S1 , and, S0.Each binary number is associated with a Boolean variable x1 through x7, corresponding to the gate structure that must ...

Flip flops are an application of logic gates. A flip-flop is a basic memory element that can save one bit of data. Flip flop has two stable states. One of the stable states is called SET or 1. The other stable state is known as RESET, CLEAR, or 0.A flip-flop ... Read More

The control inputs to registers and memory are −Load (LD) − When it is enabled, the content from the source register or memory can be transferred to/from the bus.Increment (INR) − It can increment the register by 1.Clear (CLR) − It can clear the register.The figure shows a scheme for ... Read More

Control Logic Gates is the hardware component of a basic computer. It includes various inputs and outputs. The block diagram of the control logic gates is displayed in the figure. It includes two decoders, a sequence counter, and some control logic gates.There are some instruction that is read from the ... Read More

The instructions and data that have to be calculated should be entered into the computer by the various medium. The results should be provided to the user by a medium. The Input/output structure of the computer supports a method to communicate with the external world and prepare the operating frameworks ... Read More

Memory reference instructions are those commands or instructions which are in the custom to generate a reference to the memory and approval to a program to have an approach to the commanded information and that states as to from where the data is cache continually. These instructions are known as ... Read More
