Linux Background ProcessLinux is a multitasking operating system running various process at once, including foreground to background process. Its shell also allows the user to interact with the environment and put the desired process foreground or background or even kill.Firstly list the process running by the command ps. PID values must be know to killContinue reading "Linux Background Process"

What is inode in Linux ?
What is inode in Linux ?An inode is an entry point of any table. It acts as the index to the a particular cell of table. The os relates all files and directories via inodes. Inodes are basically assigned by the inside content of the file or directory on the basis of hashing. The hashedContinue reading "What is inode in Linux ?"
Difference between Hardlink and Softlink
What is the difference between Hard Links and Soft LinksApart from the concept of pointers in C hardlinks and Softlinks work differently. Every file has an inode number. This number is like an address similar to that of your house so whoever has it can go your house. So the hardlinks knows about the address andContinue reading "Difference between Hardlink and Softlink"
Frequency Divider by 4
Continued from hereTo further divide the frequency we can use the output of D FF to the clock of another D FF and cascading the same we can divide the frequency by powers of 2.The frequency can be f/2, f/4, f/8, f/16, ..... where f is frequency of clock. For every division of frequency we need toContinue reading "Frequency Divider by 4"
Frequency Divider D Flip Flop Verilog Code
FREQUENCY DIVIDER USING D FLIP FLOPD FF can also be used as a frequency divider where the output frequency becomes exact half to the frequency of the clock signal provided to the D FF. It can be used as a binary divider or “divided by 2” format. This is done by short circuiting the Q’Continue reading "Frequency Divider D Flip Flop Verilog Code"
Master Slave D Flip Flop Verilog Code
MASTER-SLAVE D FLIP FLOPIn SR flip-flop when the conditions SET and RESET both are 1 that condition is known as a forbidden condition. This tries to change the both Q and Q’ to be 1 and whichever will turn 1 first will further control the latch which is certainly we don’t want. This can beContinue reading "Master Slave D Flip Flop Verilog Code"
Verilog Code for D Flip Flop
D FLIP FLOPD flip flop stands for Delay Flip Flop. It acts as a buffer which delays the output by a clock cycle or as per desired. It’s a bistable multivibrator. D Flip Flop stores a single bit of data at a time. It has two inputs. The first is the D. The second is theContinue reading "Verilog Code for D Flip Flop"
Verilog Code for Carry Look Ahead Adder
CARRY LOOK AHEAD ADDERWhen full adders are used they often introduce a time delay since every single bit addition depends on the carry of previous addition. Hence C4 will wait for C3 and C3 will for C2 and so on. A carry look ahead adder basically reduces the time complexity however increases theContinue reading "Verilog Code for Carry Look Ahead Adder"
Verilog Code for 8bit Full Adder
FULL ADDERHola AmigosAdders as we all have used might pose a problem when simulated for very long space complex projects as the results of full adder are not instant. It does take time and the propagation delay increases with time so how do we deal with delay caused by each gate. Here have a look onContinue reading "Verilog Code for 8bit Full Adder"
