Data Transfer Instructions : The MOV instruction is used to transfer a byte or a word of data from a source operand to a destination operand. These operands can be internal registers of the 8086 and storage locations in memory. MOV instruction cannot transfer data directly between a source and a destination that both reside […]

String Manipulation Instructions A series of data byte or word available in memory at consecutive locations, to be referred as Byte String or Word String. A String of characters may be located in consecutive memory locations, where each character may be represented by its ASCII equivalent. The 8086 supports a set of more powerful instructions […]

2.1 Read Write Timing Diagram General Bus Operation The 8086 has a combined address and data bus commonly referred as a time multiplexed address and data bus. The main reason behind multiplexing address and data over the same pins is the maximum utilization of processor pins and it facilitates the use of 40 pin standard […]

MINIMUM MODE 8086 SYSTEM AND TIMINGS In a minimum mode 8086 system, the microprocessor 8086 is operated in minimum mode by strapping its MN/MX* pin to logic1. In this mode, all the control signals are given out by the microprocessor chip itself. There is a single microprocessor in the minimum mode system. The remaining components […]

Physical address formation: The 8086 addresses a segmented memory. The complete physical address which is 20-bits long is generated using segment and offset registers each of the size 16-bit.The content of a segment register also called as segment address, and content of an offset register also called as offset address. To get total physical address, […]

Introduction: Microprocessor: It is a semiconductor device consisting of electronic logic circuits manufactured by using either a Large scale (LSI) or Very Large Scale (VLSI) Integration Technique. It includes the ALU, register arrays and control circuits on a single chip. The microprocessor has a set of instructions, designed internally, to manipulate data and communicate with […]
