Thanks dear

Ma'am ,kya ye DMA ka block diagram, hum 8237 DMA control me bna sakte hai?

[@TechnoTutorials2783]

No ye jaha define dma operation hoga waha

[@GauravJain-xk2kf]

mam as we know that in the bus structure of 8085 address bus is also connected to i/o device but while in bus structure drawing with dma ,connection of address lines with i/o devices is abesent why

[@TechnoTutorials2783]

Actually in bus structure we are showing MPU CONNECTED THROUGH address bus to IO BUT in DMA we bypass the MPU so when MPU realised control of buses then system bus will be connected with IO

mam can you plzz guide how to start studying microprocessor for aktu....as i have now started studying this subject yet.....i am feeling confident in other subjects like O.S, TAFL ,DIGITAL ELECTRONICS etc.....but i don't know how to start microprocessor...plzz any tips 🙏

[@TechnoTutorials2783]

Start with block diagram and pin diagram.of all ics 8085,8086,8255,DMA,8253 AFTER THAT addressing modes of 8085 and 8086 Then psw of 8085 and 8086 Then interrupts for both
