Similarities between macro and subroutine?
Both Macro & Subroutine are set of instructions that are called several times to perform a specific task. They act like functions that have a sequence of instructions stored and is often called by the program.

Difference between delay subroutine and ordinary subroutine in context of 8085?
a subroutine is a portion of the code within a larger program which performs a specific function and is independent of remaining code.....delay routines are subroutines used for maintaining the timings of various operations in microprocessor
Write a program to introduce a time delay using subroutine?

What is subroutine in 8085?
in 8085 microprocessor a subroutine is a separate program written aside from main program ,this program is basically the program which requires to be executed several times in the main program. the microprocessor can call subroutine any time using CALL instruction . after the subroutine is executed the subbroutine hands over the program to main program using RET instruction.
How is delay calculated in 8085?
The delay is calculated in 8085 by making the use of formulas. Because of the complexity of the mathematical operations a calculator may also be required.
Write a main program in INTEL 8085 microprocessor to count continuously in binary with a one second delay between each count?
To create a main program in the Intel 8085 microprocessor that counts continuously in binary with a one-second delay between each count, you can use the following code: START: LXI H, 0000H ; Initialize register pair HL to 0000 INX H ; Increment HL CALL DELAY ; Call delay subroutine for 1 second JMP START ; Repeat the process DELAY: MVI C, 0FFH ; Load C with 255 D1: MVI B, 0FFH ; Load B with 255 D2: DCR B ; Decrement B JNZ D2 ; Loop until B becomes 0 DCR C ; Decrement C JNZ D1 ; Loop until C becomes 0 RET ; Return from delay This program initializes a counter, increments it continuously, and calls a delay subroutine that creates a delay of approximately one second using nested loops.
What are stacks subroutines in 8085 microprocessor?
A subroutine is a group of instructions that will be used repeatedly in diff locations of the program..........rather than repeating the same instructions several times, they can be grouped into a subroutine that is called from diff locations. 8085 has 2 instruction set for dealing with subroutines: 1.CALL -direct the program execution to the subroutine. Generally it pushes address of next instruction of program counter onto the stack,then goes to the address of subroutine. 2.RET:- pops the address of next instruction from the stack and places it in the program counter and returns to that address to continue processing. For example, you have an often used value stored in HL. You have to call a subroutine that you know will destroy HL (with destroy I mean that HL will be changed to another value, which you perhaps don't know). Instead of first saving HL in a memory location and then loading it back after the subroutine, you can push HL before calling and directly after the calling pop it back. Of course, it's often better to use the pushes and pops inside the subroutine.
Write a program to add two 8 bit numbers in microprocessor 8051?
write it in 8085
Why 8085 is called parallel device?
The data bus of 8085 is 8 bit and so it will read or write 8 bits simultaneously.So it is Parallel Devise

Why is the data bus in 8085 bidirectional?
So that the processor can both read and write data.
