It is a fixed priority algorithm which assigns priorities to tasks according to their relative deadlines: the shorter the deadline, the higher the priority.
No EDF is not based on priority !! . But DMA is based on Deadlines priority . I mean to say that EDF is based on Earliest Deadlines first that is it only goes on seeing upon only upcoming earliest deadlines...!! But this DMA is purely based on least unit deadline has highest priority !!!👍👍
Sometimes, before drawing the schematic, he asks us to check the scheduling using the exact test, and so we have to write the functions of the tasks and calculate the critical points. Please how do we calculate these points. Thank you.
working with "lowest common multiple"(lcm) is mandatory to see if the system is schedulable. You have to take the lowest numbers possible to be able to see if the total execution time of the tasks is enough to meet their deadlines. 20 is lcm in this case.
the EDF priority assignment depends on the deadline and not the period, but in the case of DM the priority assignment depends on either the period value
Best videos on this topic! Super clear thanks 🙏
what is the difference between deadline monotonic and Earliest deadline first . kindly explain
Thank you very much sir, keep it up
Thanks a lot
thank you so much sir
but what the different between EDF and DM so we get the same result and both of them depend on deadline values ?

@@niranjanninja9695 Thanks for the explanation
edf is dynamic priority and chooses the next deadline, while the priority in dms is static
What is the difference of EDF from this
Same question
😅😊

Thank you.
please upload about Critical instant and Busy interval in Real time system
complicately explained, I'm confussed...
thnq sir nyc concept
thank u very much sir
Thanks

4:38 T1 not T3 !!
very nice
best video....keep carry on and wishes you got high popularity at this platform
40 is also divisible by all three task so why are we taking 20

Whatsupppppp!!!!
Sir questions eppadi kepangae
Sir pura complete video real time system ka bana dijiye please exam parso hai🙏
isnt it the same as EDF? what is the diffference betweeen EDF and DM ?
the difference between EDF and DM is that the first one is not based on priority but the last one yes it depends on deadline values
Edf you follow deadline dynamically aka each second passes you check your priorities while dm is static prior
Dm and edf are same so why different videos?
They're not the same. EDF is dynamic priority. DMS is static priority and all the tasks are periodic.
@@gauthamkrishnan5948 but same calculation?

Sirf 3 unit hi aa raha hai
so its non- premptive
Thanks
