Digital Logic and Microprocessors

This arithmetic instruction in 8086 adds two binary operands and a carry and places the result in the destination.

This addressing mode in 8086 is the way to specify the location of an operand to memory.

A NOR gate outputs ON (logic 1) only when all inputs are OFF (logic 0). The NOR operation is equivalent to NOT-OR: it outputs 1 only when all inputs are 0, and outputs 0 if any input is 1. This makes it the logical complement of the OR gate.

This bit of status register in the architecture of 8087 co-processor is used for over flow error that indicates a result which is too large to be represented.

STO SB meand Store Byte to String. This instruction is used in 8085 to store a byte from AL into a string location in memory.

This main part of Execution Unit is a 16-bit register having 16 flip flops that shows the condition or changes produced by the execution of an instruction.

This data transfer instruction in 8086 microprocessor is used to copy data from source memory location to destination.

Pin 8086 is a bus high enable signal that shows the data transfer over the higher order (D15-D8) data bus.

This pair of registers in general purpose registers is used as a memory pointer in data segment and is also used for based indexed and register indirect addressing modes.

This instruction in 8086 microprocessor is used for signed multiplication.

STI stands for Set Interrupt. This is a flag manipulation instruction in 8086, which is the interrupt flag set by the instruction that helps processor to identify the maskable interrupt on INTR pin.

It is a physical device which performs a logical operation on one or more logical inputs.

An array of flip-flops is known as register. So, this is the correct answer.

Demultiplexer has a single input data and multiple output. So, this a correct option.

Stack are 16-bit segment registers used to contain data and return addresses of procedures or subroutines.
