Data Transfer Instruction 8086 8086 Microprocessor by Ravinder Nath Rajotiya - October 14, 2020October 14, 20200 Data Transfer Instructions These instructions are used to transfer the data from one operand to another. The source operand could be a literal, in a register, memory, or even an i/o port, as the case may be. Examples of data transfer instructions are: MOV, XCHG, XLAT, LEA, LDS, LES, PUSH, POP, IN and OUT. These instructions are described in the following paragraphs. MOV : Move byte or word to register or memory location. The source can be a register, memory location or an immediate number, the destination can be a register or memory location. But bot the source and destination cannot be memory locations. General syntax format : MOV Destination, Source Examples: MOV CX, 023Bh ; move an immediate 16-bit number in register CX MOV AX,
Instruction Set 8086 8086 Microprocessor by Ravinder Nath Rajotiya - October 14, 2020April 28, 20210 Platforms for writing 8086 assembly programs. Assembly level language program for the 8086 processors can be written in the following platforms. Directly as hex codes fed into the RAM and executed on a trainer kit DOS debug utility of windows Writing the text file in notepad or gedit and then assembling using the MASM, TASM, NASM assemblers etc. We can also write and run the program in the IDE of C or C++ Classification of instructions 8086 instructions may be classified as: Classification based on size of the instruction: As discussed in topic on instruction format 8086 instruction can be from 1 to 6 byte long. The first two bytes indicate the OPCODE and the addressing Classification based on the addressing modes: The

8051 Experiment-1: Introduction to KIT ET-8031/51 8051 Expriments by Ravinder Nath Rajotiya - October 10, 2020May 27, 20210 Introduction to Hardware ET-8031/51 KIT: General: 8-bit 8031/8051 microcontroller operating at 10/12 MHz with on-chip oscillator and clock circuit, 8 i/o lines, two 16-bit timers/counters, five sources of interrupt structure. 64 KB of external program memory and 64 KB of data memory. Memory: Kit has 8KB RAM using IC 6264 and 32KB of EEPROM monitor using IC 27256 There is a memory space provided for memory expansion, the space can be defined for an address from 4000 – FFFF depending upon size of memory chip to be used. I/O Devices: The kit uses 8279 programmable KB-display controller, 8253- programmable interval timer, 8255 –programmable peripheral interface, peripheral chips. These are explained below: 8279 –Programmable KB and display controller:It is a general
