About

You will be able to

Explain the architecture, pin diagram, registers, flags and buses of the 8085 microprocessor
Classify 8085 instructions and addressing modes and find instruction size
Write assembly language programs for arithmetic, data transfer, loops, delays and subroutines
Explain stack operations and timing diagrams (basic)
Interface memory and I/O devices using address decoding and the 8255 PPI
Explain 8085 interrupts and the use of peripheral chips (8253, 8259, 8257)

Who it is for

Diploma engineering students of Semester 4 (BTEUP) - Computer Science & Engineering, Electronics Engineering
Polytechnic students who need regular coaching, revision and practice for the BTEUP semester examination

What you need

Digital Electronics (number systems, logic gates, flip-flops)

Questions

Which syllabus does this course follow?

It follows the BTEUP (Board of Technical Education, Uttar Pradesh) syllabus of Microprocessors (Semester 4). Where your polytechnic follows a different board or a revised syllabus, the centre follows your own syllabus.

Will it help in the semester examination?

Yes. Every unit is covered with solved examples, unit-wise MCQs and previous-year style questions for the BTEUP theory and practical exams.

Is assembly programming done on a kit?

The theory is taught here with hand-coded programs; programs are run on 8085 kits or a simulator in the Microprocessors Lab.
