8085 is a Microprocessor which was developed by Intel in 1970s. All the instructions in this microprocessor are encoded in a single byte. Some of the instructions are followed by one or two bytes of data, which can be a memory address, an immediate operand or a port number.

In this post, we will write a program in 8085 to calculate 8-bit sum of N 8-bit numbers.

### Algorithm

Start Address <- 2400H C <- M[Address] A <- 0 Address <- Address + 1 A <- A + M[Address] C <- C - 1 If C is not zero, goto 4 Address <- Address + 1 M[Address] <- A Stop

### Flow Chart

### Program

LXI H, 2400H MOV C, M MOV A, 00H BACK: INX H ADD M DCR C JNZ BACK INX H MOV M,A RST 5

### Example

2400H: 04 2401H: 01 2402H: 02 2403H: 03 2404H: 04 2405H: 0A -> Output
