The 8085 is an 8-bit microprocessor introduced by Intel in 1976. It's widely used in embedded systems and for educational purposes.
The 8085 has seven 8-bit registers: A (Accumulator), B, C, D, E, H, and L. The A register is special and is used in many arithmetic and logical operations.
The 8085 can address up to 64KB of memory. Memory is organized as a sequence of 8-bit bytes, each with a unique 16-bit address.
Let's start with some basic instructions: MOV (move data), MVI (move immediate data), and LDA/STA (load/store accumulator).
The 8085 supports basic arithmetic operations like ADD (addition) and SUB (subtraction). These operations typically involve the accumulator.
Instructions like JMP (jump) and JZ (jump if zero) allow you to control the flow of your program based on certain conditions.
