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 convert binary number to binary coded decimal(BCD).
Algorithm
Start Read binary number(C) Clear accumulator(A) D <- 0 A <- A + 1 Adjust for BCD count If CS != 1 go to 9 D <- D + 1 C <- C - 1 if CS != 0 go to 5 Store A as lower bits Store D as upper bits Stop
Flow Chart
Program
LXI H, 2100H
MVI D, 00H
XRA A
MOV C, M
LOOP: ADI 01H
DAA
JNC SKIP
INR D
SKIP: DCR C
JNZ LOOP
MOV L, A
MOV H, D
SHLD 2201H
RST-5
Example
2100H: F0 2101H: 40 -> lower bits 2105H: 02 -> upper bits // output is 240
