Interfacing
of Memory and I/O devices :
Concept of address space, address/data bus
demultiplexing, address and data bus buffering, address decoding, I/O
concepts, memory interfacing concept of I/O mapped I/O and memory mapped I/O.

Assembly
Language Programming :
(This part may be limited to the use assembly
language of 8085 or 8086/8088 CPU) i) Example for register to register,
register to memory, memory to register, block of data movement from one area
of memory to another, merging of two blocks of data, data block exchange. ii)
Examples of arithmetic addition, subtraction, multiplication and division
iii) Examples of searching and
sorting (simple) iv) Examples using of look up tables v) Use
subroutines and delay programme.
