Getting the sense for jumps and flags has long been a troublesome area for me, especially since the Intel assembler book shows 32 of these, all with similar-sounding names. Looking more closely I found that many of th...

In this article, we will discuss branch instructions which are supported by the 8086 microprocessor. We will also discuss assembly language programming examples of conditional branch instructions. 8086 Types of branch...
Complete 8086 instruction set When two operands are required for an instruction they are separated by comma. For example: REG, memory When there are two operands, both operands must have the same size (except shift an...
Prerequisite - Branching instructions in 8085 microprocessor Program execution transfer instructions are similar to branching instructions and refer to the act of switching execution to a different instruction sequenc...
REG: AX, BX, CX, DX, AH, AL, BL, BH, CH, CL, DH, DL, DI, SI, BP, SP.
x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. Previous evolutions of this family of languages provide backward compatibility...
The 8086 microprocessor supports 8 types of instructions − Let us now discuss these instruction sets in detail. These instructions are used to transfer the data from the source operand to the destination operand.
Generally, when it is required to compare numeric values CMP instruction is used (it does the same as SUB (subtract) instruction, but does not keep the result, just affects the flags). The logic is very simple, for ex...
The JB instruction in 8051 assembler jumps to the address indicated by the label in the second operand if the bit specified by the first operand is set. So in your case it will jump to MOV P0,#0FFH if P0.7 is set. The...
