PPT-Instruction Set of 8086 Microprocessor

1 Instruction An instruction is a binary pattern designed inside a microprocessor to perform a specific function Opcode It stands for operational code It specifies the type of operation to be performed by CPU. g ADD eax5 Add 5 to contents of accumulator No memory reference to fetch data Fast Can have limited range in machines with fixed length instructions Immediate Addressing and Small Operands A great many immediate mode instructions use small operands 8 Address Decoding. Topics to be discussed. ADDRESS DECODING . A simple NAND gate decoder . Sample Decoder Circuit . The Dual 2-to-4 Line Decoder (74LS139) . PLD Programmable Decoders . ADDRESS DECODING. Microprocessor Architecture. Some points to recollect. Microprocessor Architecture. Machine code. Every CPU has its own machine . language.each. instruction has its unique numeric code called . opcode. Interrupt. Normal . prog. execution is interrupted by . Some external signal, or. A special instruction in the . prog. In response to an interrupt, . the mp stops executing its normal . prog. &. J . Srinivasa. Rao. Govt. Polytechnic . Kothagudem. Khammam. 2. Microprocessor.
