Hardware Questions

1.Limitations on the size of data. 

2.Most Microprocessors does not support floating-point operations. 

3.Over heating physically

4. Not bit addressable

The data bus is Bi-directional because the same bus is used for transfer of data between Micro Processor and momory of input / output devices in both the direction.

The Quality Factor is also defined, as Q. So it is a number, which reflects the lossness of a circuit. higher the Q, the lower are the losses.

the quality factor is measurement of efficiency (or effectiveness) of a device or circuitry. In literal sense quality factor means qualitative performance of a device.

Floating gate avalanche injection MOS (FAMOS) transistor is used in each cell of EPROM.

In microprocessor more op-codes, few bit handling instrucitons. But in Microcontroller. fewer op-codes, more bit handling Instruction, and also it is defined as a device that includes micro processor, memory, & input / output signal lines on a single chip.

the basic architectual difference is that microcontroller has an programmable memory while it is not the case with mivroprocessors.

INPLEMENTATION:

For SUM, The two inputs A and B are given to XOR gate.

For Carry, The two inputs A and B are given to AND gate.

An interrupt that can be turned off by the programmer is known as Maskable interrupt.

In 8086 Carry flag, Parity flag, Ausiliary carry flag, Zero flag, Overflow flag, Trace flag, Interrupt flag, Direction flag, and Sing flag.
