Why DCX D instruction have 6 T states in 8085 microprocessor?
3 T states for instruction fetch, 1 T state for decode, 1 T state for register E decrement, 1 T state for possible register D decrement.
What is meaning of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel.
What are the general purpose register in 8085 microprocessor?
6 general purpose registers.i.e., B,C,D,E,H,L
What is 8085 architecture?

How much space did the Intel 8080 microprocessor have?
The stack size of Intel's 8085 microprocessor is theoretically 64 kb, but the real limit is a function of memory and program architecture and layout. The stack pointer is 16 bits, but that is not the same as stack size.

Draw a schemetic to demultiplex bus ad0-ad7 using any octal latch in 8085 microprocessor?
The 8085 microprocessor is used IC 74LS373 to latch the address of 8085. Basically latch is consists of 8 flip flops. Generally we used D-flip flops (Delay).The clock of these flip flops are connected together and available as a output pin called enable.Working : The address will appear on AD0 AD7 lines. The ALE will go high and forcingEnable = 1. This will make latch enable and ready to work. Before address disappears ALE = 0. This will make latch disable. AD0 - AD7 will now be used as data bus.Hence, AD0 - AD7 (low order) address bus of the 8085 microprocessor is multiplexed (time-shared) with the data bus. The buses need to be demultiplexed.
