Inc instruction in 8086

Jump Instructions are used for changing the flow of execution of instructions in the processor. If we want jump to any instruction in between the code, then this can be achieved by these instructions. INC AX INC [BX] INC [5000H] DEC : Decrement The decrement instruction subtracts 1 from the contents of the specified register or memory location. Strings and String Handling Instructions : The 8086 microprocessor is equipped with special instructions to handle string operations. 8086 Instruction Encoding-1. Instruction Format (Cont'd) ! Instruction may also be optionally preceded by one or more. prefix bytes for repeat, segment override, or lock prefixes In 32-bit machines we also have an address size override prefix and an operand size override prefix ! INC WORD PTR [BX] Increment the word at offset of [BX] and [BX + 1] ? INC TEMP in the data The 8086 allows you to subtract the ASCII codes for two decimal digits without masking the "3" in the LOGICAL INSTRUCTIONS AND - AND Destination, Source This instruction ANDs each bit in a Intel 8086 Instruction Timing. 1.

The 8086 has separate I/O and memory address spaces. Values in the I/O space are accessed with IN and OUT instructions. The port address is loaded into DX and the data is ; increment BX INC BX. ; compare (subtract and set flags ; but without storing result). CMP AX,[MAX] ; mask in LS 4 bits of AL.

The 8086 processes of arithmetic and logic unit has separated into three groups such as addition, division, and increment operation. Most Arithmetic and Logic Instructions affect the processor status register. The assembly language programming 8086 mnemonics are in the form of op-code, such as ? The jal instruction saves the address of the next instruction in $ra before transferring control to a function. ? Conventions are used for passing ? Control flow for 8086 function calls involves two aspects. — The CALL instruction is similar to jal in MIPS, but the return address is placed on the
