8086 Microprocessor Pin Diagram and 8088 Pin Diagram: In order to implement many situations in the microcomputer system the 8086 Microprocessor Pin Diagram and 8088 Pin Diagram has been designed to work in two operating…
Interrupt Priority in 8086: As far as the Interrupt Priority in 8086 are concerned, software interrupts (All interrupts except single step, NMI and INTR interrupts) have the highest priority, followed by NMI followed by INTR.…
8086 Interrupt Types: The 8086 Interrupt Types are Dedicated Interrupts: Type 0 : Divide by Zero Interrupt When the quotient from either a DIV or IDIV instruction is too large to fit in the result register;…
Interrupt Structure of 8086: An Interrupt Structure of 8086 can come from any one the three sources : External signal Special Instruction in the program Condition produced by instruction External Signal (Hardware Interrupt): An 8086…
Conditional Statement in Assembly Language Program: Assembler supports the use of Conditional Statement in Assembly Language Program. It also allows to use them in macro sequences. These conditional statements control the flow of the program…
Macros in Microprocessor: Macro is a group of instructions. The Macros in Microprocessor assembler generates the code in the program each time where the macro is 'called'. Macros can be defined by MACRO and ENDM…
Parameter Passing Techniques in Microprocessor: Parameter Passing Techniques in Microprocessor - Whenever we need to use a group of instructions several times throughout a program there are two ways we can avoid having to write…
Modular Programming in 8086 Microprocessor: Many programs are too large to be developed by one programmer. Such programs are developed by team of programmers. They divide a large program into smaller modules. Then each Modular…
Assembly Instruction Format: Although each Assembly Instruction Format has its own unique syntactical structure, such as requiring upper case or lower case, or requiring colons after label definitions we discuss the common features that assembler…
Program Development and Execution: The steps involved in Program Development and Execution of assembly language programs. Fig. 8.1 shows these steps. The left side of the figure shows the time period, at which each step…
