How to Program with 8085 Microprocessor




Now that you have downloaded and installed the ebook pdf and the programs, let us see how to program with 8085 microprocessor. In this section, we will cover some of the basic concepts and components of 8085 microprocessor architecture, how to write, assemble, debug and run 8085 assembly language programs, and how to use various operations and features of 8085 microprocessor.


What are the basic concepts and components of 8085 microprocessor architecture?


The 8085 microprocessor architecture consists of three main components: arithmetic logic unit (ALU), registers and control unit. These components are interconnected by three buses: data bus, address bus and control bus. The following diagram shows a simplified view of 8085 microprocessor architecture:


+-----------------+ +-----------------+ +-----------------+ Arithmetic Registers Control Unit Logic Unit (ALU) +-----------------+ +-----------------+ +-----------------+ ^ ^ ^ ^ ^ ^ +------------------+ +------------------+ +----------------------------------------------+ v +-----------------------------------------------------+ Buses Data Bus: Carries data between ALU, registers and memory or I/O devices Address Bus: Carries address of memory or I/O devices to be accessed Control Bus: Carries control signals to direct the operation of microprocessor +-----------------------------------------------------+


The ALU is the component that performs various arithmetic and logic operations on binary data, such as addition, subtraction, multiplication, division, complement, shift, rotate, compare, etc. It also sets the flags in the flag register according to the result of the operation.


The registers are the component that store binary data temporarily during the execution of a program. They are classified into two types: general purpose registers and special purpose registers. The general purpose registers are used to store data or operands for ALU operations. They are named as A, B, C, D, E, H and L. The special purpose registers are used to store specific data or information for microprocessor operations. They are named as program counter (PC), stack pointer (SP), accumulator (A), flag register (F), instruction register (IR) and temporary register (TMP).


The control unit is the component that controls the overall operation of the microprocessor. It fetches the instructions from memory, decodes them, executes them and generates the control signals for ALU, registers and buses. It also handles the interrupts and timing signals.


How to write, assemble, debug and run 8085 assembly language programs?


To write, assemble, debug and run 8085 assembly language programs, you need to follow these steps:



  • Write the program in a text editor using 8085 assembly language syntax and mnemonics. Save the file with a .asm extension.



  • Assemble the program using the 8085 simulator program or the ENV185 program. This will convert the assembly language code into machine language code and generate a .hex file.



  • Debug the program using the 8085 simulator program or the ENV185 program. This will allow you to check and correct any errors or bugs in your program. You can use various features such as breakpoints, single-step execution, memory dump, register display, etc.



  • Run the program using the 8085 simulator program or the ENV185 program. This will execute your program and display the output on the screen or on any connected device.



How to use various operations and features of 8085 microprocessor?


To use various operations and features of 8085 microprocessor, you need to understand and apply the following concepts:



  • Addressing modes: These are the ways of specifying the location of data or operands for an instruction. There are five addressing modes in 8085 microprocessor: immediate addressing, register addressing, direct addressing, register indirect addressing and implied addressing.



  • Instruction sets: These are the sets of instructions that can be executed by 8085 microprocessor. There are three instruction sets in 8085 microprocessor: data transfer instructions, arithmetic and logic instructions, and control transfer instructions.



  • Data transfer operations: These are the operations that transfer data between registers, memory or I/O devices. Some of the data transfer instructions are: MOV, MVI, LXI, LDA, STA, LHLD, SHLD, LDAX, STAX, XCHG, etc.



the arithmetic and logic instructions are: ADD, ADC, SUB, SBB, INR, DCR, INX, DCX, DAD, SUI, SBI, ANI, ORI, XRI, CPI, RLC, RRC, RAL, RAR, CMA, CMC, STC, DAA, etc.


  • Branching and looping operations: These are the operations that change the sequence of execution of a program based on certain conditions or repetitions. Some of the control transfer instructions are: JMP, JC, JNC, JZ, JNZ, JPE, JPO, JP, JM, CALL, CC, CNC, CZ, CNZ, CPE, CPO, CP, CM, RET, RC, RNC, RZ, RNZ, RPE, RPO, RP, RM etc.



  • Stack and subroutine operations: These are the operations that use a special memory area called stack to store and retrieve data or return addresses during the execution of a program. The stack is a last-in first-out (LIFO) data structure that can be accessed using the stack pointer (SP) register. Some of the stack and subroutine instructions are: PUSH, POP, XTHL, SPHL, PCHL etc.



  • Interrupt operations: These are the operations that allow the microprocessor to respond to external events or signals that require immediate attention. The 8085 microprocessor has five hardware interrupts and one software interrupt. The hardware interrupts are: INTR (maskable), RST 5.5 (maskable), RST 6.5 (maskable), RST 7.5 (maskable) and TRAP (non-maskable). The software interrupt is: RST n (where n = 0 to 7). Some of the interrupt instructions are: EI (enable interrupt), DI (disable interrupt), SIM (set interrupt mask), RIM (read interrupt mask), etc.



  • Advanced topics: These are some of the advanced topics that cover the latest developments and trends in microprocessor technology. Some of them are: microcontrollers (single-chip microcomputers that integrate CPU with memory and I/O devices), embedded systems (special-purpose computer systems that perform specific tasks within larger systems), digital signal processors (specialized microprocessors that process digital signals such as audio and video), etc.
