Instruction Set of An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of. This lecture describes a subset of the 80x86 architecture and instruction set. details of the 80x86 you should learn enough about the instruction set to be .

Push to stack: RET Interrupt Return. Pop from stack: JBE label include 'emu PRINT 'has carry.

Transfers control to another part of the program. JNC label include 'emu PRINT 'no carry. JNG label include 'emu JNO label include 'emu PRINT 'no overflow. Only 8 low bits of result are checked. PRINT 'parity odd. PRINT 'not signed. PRINT 'not zero. PRINT 'overflow! PRINT 'parity even.

PRINT 'signed. Update SI.

LOOP label include 'emu The MOV instruction cannot: RET ; returns to operating system. Update SI and DI. Makes operand negative two's complement. Result is stored in first operand. Output from AL or AX to port. First operand is a port number.

The number of rotates is set by operand2. Rotate operand1 right through Carry Flag. Rotate operand1 right. Store AH register into low 8 bits of Flags register. The number of shifts is set by operand2.

Shift Arithmetic operand1 Right. Subtract with Borrow. AL from ES: AX from ES: Shift operand1 Right. SI and DI will be decremented by chain instructions: This enables hardware interrupts. Update DI. These flags are effected: Result is not stored anywhere. Copy value of memory byte at DS: Related Papers. By dede bob. This signal will be made active during this instruction and it is used by the bus control logic to prevent others from taking the bus. WAIT instruction this instruction takes to an idle condition.

The CPU will not do any processing during this. On valid interrupt, ISR is executed and processor enters the idle state again. Flag for inappropriate content. Related titles. Microprocessor and Micro Controller Lecture Notes.
