Clock

Clock is the heart of any electronics hardware device that calculates,provides delay etc.Clock is essential in every hardware that needs a repetion like generating a ramp wave in multimeter, increasing or decressing a speed of processor, It is use almost in every device.

Clock is given using crystal oscillator, cmos ic etc.

Clock can be understanded better by student and bell example in schools

In Processor Clock impacts speed in following ways

---Raising a clock

---Dividing a clock by some factor (>1 i guess) i guess---gives more no. of cycles(Combination of each tick(1) tack(0) is known as cycle)-->fasten the speed

---Multiplying a clock by some factor (>1 i guess)---gives less no. of clock cycles (I guess if multiplication factor is greater than 1.obviously ! if it is less than 1 then it would indirectly be a division ...decimal removed ..no go down ...lab ! lab!. --> ultimately in these as time period increases therefore,no of clocks come after huge huge interval -->and thus speed reduces.

there are also many other factors to increase speed of processor beside clock like

--Pipelining
--Parllelism
--Increasing Cores of CPU
--Increasing No.  of bits like make a 64 bit ......the advantage of this reflects in high end graphics games....and not much in small programs....that is by increasing number of bits you mean to increase the data rate at a fix interval of time

FSM

 

In above code you have maded two always{procedural} blocks because your “y” {past state} is a level sensitive in first always block and negedge clk is the edge triggered in your second always procedural block therefore,it is a rule you can’t write both edge triggered as well as level triggered in same sensitivity list.

Kinds of Signal While Analyzing a Waveforms

Differntial Pair Signalling

you can see here we mix two different kinds of waves in it .

Why we use these kinds of signal?

Ans. Because you get much higher speed with these signals

PSHDL

You can do PSHDL coding in cloud itself

In PSHDL if you just write

1. module MyFirstModule{
2. register uint<17> counter=counter+1;
3. }

it means the system will count at rising edge of every count

But in case you want a register to count at falling edge then in that case you have to write code as follow:-

1) Adding a Two Number using PSHDL

Do you Know How Actually Simulation is coming out on Browser? The answer to this is you have converted your code into javascript.

2) Making a Counter Using PSHDL

1. module MyFirstModule{
2. register uint<17> counter=counter+1;
3. out bit led=counter(13);
4. }

And your output will be blinking led as shown on that screen

Now you can yourself see How simple is this PSHDL
