Q. Explain Hardwired control organization?
In the hardwired organization control unit is designed as a combinational circuit. The control unit is applied by gates, flip-flops, decoder and other digital circuits. Hardwired control units can be optimised for fast operations. Block diagram of control unit is displayed in Figure below. Major inputs to circuit are instruction register, clock, and flags. Control unit uses the opcode of instruction stored in IR register to perform various actions for various instructions. The Cu logic has unique logic input for every opcode. It simplifies the control logic. This control line selection can be executed by a decoder.
A decoder will have n binary inputs and 2n binary outputs. Every one of these 2n different input patterns will trigger a single unique output line.
Clock part of the control unit issues a repetitive sequence of pulses for SS duration of micro-operation(s). These timing signals control the sequence of execution of instruction as well as determine what control signal requires to applied at what time for instruction execution.

What is MASK OPERATION The mask operation is similar to selective-clear operation except which the bits of Aare cleared only where there are corresponding 0's in register B. th

ADDING LAYERS TO THE TIMELINE AND GIVING MOTION TO THE LAYER Step 1: Choose Layer from Common toolbar after that draw a layer. Step 2: Write the text inside Layer. Step
Continuing in main, write a loop that will read from the ifstream that reads enough information to create a person object (i.e. first name, last name, and weight). Exit the loop
WAR (write after read) - Data hazards in computer architecture: WAR (write after read) - j tries to write at destination before it is read by i , hence i wrongly gets the n
Why do we need DMA? DMA is used to transfer the block of data directly among an external device and the main memory without the continuous intervention by the processor.
