i dont know how should i thank to you, i have been reading assembly language book but dont understand but now i am a little bit understand , thank you very much, your teaching with annimation open my eye , you are genius teacher
Hello Andrew, Thank you for your generous comments. Best wishes Phil PS Check out the Google circles I have created for more information they can be located via the about tab RUclips About Tab. Perhaps you would like to subscribe to these circles?
sudhanshu gupta A stack pointer is a register that stores the address of a machine code instruction that is to be executed when returning from a subroutine. It is also used to store the data from all registers that contain relevant data when a subroutine is called. It is a specialised buffer which stores data/addresses from the top down. As new data/address are stored on a stack they "push down" the older ones and the data/addresses are “popped off” a stack when being retrieved. A memory address register (MAR) is a buffer register used to store address patterns before they are placed on the address bus these patterns are used to select a specific memory location.
That is it for the syllabus but there are many more addressing modes they are just not part of the syllabus. So the answer is yes that is it for the CS exam. However, there are many instructions for each type of addressing mode only one for each type has been covered in the playlist so far. Bw Phil
Thank you for you videos. And I still wonder how does cpu know it's "immidiate addressing" or "absolute addressing", cuz the two instructions both hava same opcode Load.
just watched all 4 vídeos, Worthed it, more than some hours on books.

i guess this is the only video on youtube which explains how assembly language and the processing works. Great work . thanks for the video
Thank you for your positive comments.

just one question though. Is stack pointer same as mar?

ohk. thanks a lot
This is very helpful and very to understand, hope you keep making more of these!
Thank you so much! All of these videos helped a lot.
Glad they helped thanks for commenting

Thank you so much
really helpful contents! much thanks
Thank you.. Videos helped a lot...
Very Well Explained.
Very very great!
Thank you!
Hope the exam went well
Phil
Ah thanks Phil, just checking. Better ask than panic in the exam :)

Don't panic Mr Mainwaring. Good luck with your exam.

tnx a lot sir!
Thanks for putting this one up Phil, is this now all 3 Addressing types needed for the CS exam?
Thank you for you videos. And I still wonder how does cpu know it's "immidiate addressing" or "absolute addressing", cuz the two instructions both hava same opcode Load.
The opcode is the binary pattern usually represented by a hexadecimal number. These instructions do not have the same of op code.
Best wishes Phil
need more
:-)
yeah it did, must be the same person who makes these videos writes the exam papers haha :)
Haha "I'm in charge now"
