MULTIPROCESSOR CONFIGURATION & COPROCESSOR CONFIGURATION OF 8086.

Define microprocessor 8086.

8086 microprocessor-16 bit, logic unit, internal register.

Define multiprocessor.

Mu!iprocessor-multiplexed address, memory location, data transfer.Mention the need for multiprocessor system.

Mu!iprocessor s"s!em-cost ratio, modules, cheaper.List the advantages of multiprocessor system.

Mu!iprocessor #$%#!#'es-complex processor, less time, interprocessor.

rite the demerits of multiprocessor system.

Mu!iprocessor $emeri!s-interrupt net!or", operating system, high delay.

hat are the applications of multiprocessor system#

Mu!iprocessor #ppic#!ios-loosely coupled, closely coupled, inter processor.

hat are the three basic configurations that the 8086 can support

8086 co(i'ur#!io-interconnection, cross bar, common buses.

Define coprocessor. No%-0)

Coprocessor-more components, instructions, execution.

hat is mean by coprocessor configuration#

Coprocessor co(i'ur#!io-memory module, local memory, processor.Define master slave processor.

M#s!er s#%e processor-interrupt, coupled system, private cache.

Dra! the structure for interaction bet!een 8086 and coprocessor.

8086 #$ coprocessor-fetch message, cloc" generator, system bus.Mention the functions of coprocessor.

Coprocessor (uc!ios-instruction se$uence, %&' decode, (%&( pin.

List the advantages of coprocessor.

Coprocessor #$%#!#'es-faulty processor, multiprocessor, modular processing.

rite the disadvantages of coprocessor.

Coprocessor $is#$%#!#'es-memory less, time delay, cloc" generator.

Define 808) microprocessor.

808) microprocessor-parallel tas", bus control, system bus.hat is mean by %&' assembler language#

ESC #ssem*er #'u#'e-'*+, -( instruction, (%&( pin.

Mention the operands of %&' assembler language.

ESC #ssem*er oper#$s-setup, independent processor, interrupt re$uest.

rite about 808) register.

808) re'is!er-local register, system bus, control logic.

hen coprocessor instruction can be executed#

Coprocessor is!ruc!io-bus allocation, all masters, controller.

rite short notes on external opcode.

E+!er# opco$e-bus grant, bus re$uest, bus busy.rite about interaction bet!een 8086 and 808).

8086 #$ 808)--/ devices, local bus, system memory.Mention the applications of 808) microprocessor.

808) #ppic#!ios-data buffer, co processor, load constant.

List the operations of 808) $ueue status signals.

808) oper#!ios-arithmetic module, micro code, data buffer.

Mention the uses of -( instructions.

,AIT is!ruc!io uses-source operand, destination operand, string operand.

Mention the uses of 808) register.

8087 register uses-trap flag, interrupt flag, pipelining.
