9 Module I Introduction: Microcomputer & Microprocessor A microcomputer is a programmable machine. Modern computers are electronic and digital. The two principal characteristics of a computer are: It responds to a specific set of instructions in a well-defined manner. It can execute a prerecorded list of instructions (a program) Its main components are CPU Input & Output devices memory A microprocessor is a programmable VLSI chip which controls and performs all operations in a microcomputer. Its main units are- ALU Registers Control Unit
11 Hardware All general-purpose computers require the following hardware components: Memory: Enables a computer to store data and programs. Mass storage device: Allows a computer to permanently retain large amounts of data. Common mass storage devices include disk drives and tape drives. Input device: Usually a keyboard and mouse are the input device through which data and instructions enter a computer. Output device: A display screen, printer, or other device that lets you see what the computer has accomplished. Central processing unit (CPU): The heart of the computer, this is the component that actually executes instructions.
12 Software The programs and data stored in a microcomputer is called as software. Programs can be written in low level languages or high level languages. A low level language can be binary language or assembly language. A CPU recognizes only binary language which is called as machine language. Assembly language instructions contain alphabets and/or numeric characters. To run assembly language programs a converter called as assembler is required. High level languages are more user friendly and contain simple words of English language. To run high level programs, converters such as compilers or interpreters are required.
13 Input & Output Devices Input devices are used to input electrical or physical information in a microcomputer system in digital form. In embedded applications, commonly used input devices are simple switches and sensors. In general purpose microcomputers, input devices can be keyboards, scanners, mouse etc. Output devices are used to display or perform required operation. In embedded applications commonly used output devices are LED display units, LCD display units, stepper motors etc. In general purpose computers output devices are mainly CRTs, LCD screens, LED screens, Printers etc.
14 Memories Memory in a microcomputer system is used to store data and programs temporarily or permanently. The memories of primary concern for the CPU are only RAM & ROM which are called as primary memory or main memory. The CPU, at any time, only communicates with RAM & ROM. Other than primary memories, there are also secondary memories which are used for mass storage of data and programs and are transferred to the primary memory when required to be executed by the CPU. Examples of secondary memories are Hard Disks, Floppy Disks, DVDs, flash drives etc.

21 8085 Architecture Contd.. ALU Arithmetic & Logic Unit ALU of 8085 performs 8-bit arithmetic & logical operations. The operations are generally performed with Accumulator as one of the operands. The result is saved in accumulator register. Timing & Control Unit This unit works as the brain of the CPU and generates all the timing and control signals to perform all the internal & external operations of the CPU. Instruction Decoder & Machine Cycle Encoder Unit This unit decodes the op-code stored in the Instruction Register (IR) and encodes it for the timing & control unit to perform the execution of the instruction.
22 Instruction Set Instruction set of 8085 can be classified in following groups: Data Transfer Instructions These instructions can perform data transfer operations between Registers of 8085 e.g. MOV 8085 registers and main memory e.g. LDA, STA, MOV, LDAX, STAX, MVI, LXI etc. Accumulator register and I/O devices e.g. IN, OUT Data transfer instructions never affect the flag bits
23 Instruction Set Contd.. Arithmetic Instructions 8085 can perform only 8-bit addition, subtraction and compare operations. These operations are always performed with accumulator as one of the operands. The status of the result can be verified by the contents of the flag register. Op-codes for arithmetic instructions include ADD, ADI, ADC, ACI, SUB, SUI, SBB, SBI, CMP, CPI Logical Instructions 8085 can perform 8-bit basic logical operations -AND, OR, XOR, NOT with some special operations such as rotate and shift operations Logical instructions also modify the flag bits. Op-codes for logical instructions include ANA, ANI, ORA, ORI, XRA, XRI, CMA, RAL, RLC, RAR, RRC etc.
24 Instruction Set Contd..

33 Interfacing Contd.. I/O Interfacing To interface Input Devices Octal buffers are used. These octal buffers are called as input ports Octal buffers contain a set of eight buffers for an 8-bit system data bus A buffer is basically a current amplifier which amplifies the smaller magnitude currents of input devices before being supplied to the CPU The tri-state logic also provides the addressing and control logic for the CPU
34 Interfacing Contd.. To interface output devices Octal Latches are used. A latch is basically a D Flip-Flop Latches are used to hold the output data because information on system data bus is available for a very small duration of time. I/O interfacing techniques
35 I/O structure of 8085
36 Interfacing Contd.. There are three major types of data transfer between the microcomputer and art I/O device. They are- Programmed I/O : In programmed I/O the data transfer is accomplished through an I/O port and controlled by software. Interrupt driven I/O : In interrupt driven I/O, the I/O device will interrupt the processor, and initiate data transfer. Direct memory access (DMA) : In DMA, the data transfer between memory and I/O can be performed by bypassing the microprocessor.
37 Interfacing Contd.. Some special purpose programmable devices used with 8085 are listed in the table of next slide. These devices are used in the system according to the requirement.
