hello,
in 8085 microprocessor, accumulator is used to hold data as well as shifting. as it is a register, how it can shift data. also in 8086 cx register is additionally used to increment. how it is possible?.

and one more doubt is, as rd, wr, Io/m signals are available, why the signals iord, iowr, mrd, mwr signals are generated? please anyone clear my doubts.
 

I think you need to read something.

You apparently have very little understanding of digital electronics and microprocessors, and there is not enough space or time here to give you the basics you need before you start playing with microprocessors.
 

what is the number system of machine code of 8085 microprocessor?

binary
hex
octal
bcd

You can use any number system you want. In the very early days of the 8080 octal was commonly used, but using hex won out, so that nobody uses octal anymore.
 

I don't think BCD is a convenient number system to use in the machine code of any processor, due to the groups of missing combinations.

The Decimal number system could be used, if you tend to be masochistic.
 

thank you all
