Microprocessors - Question and Answer - 7

31. What does Quality factor mean?
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. Quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the peak energy stored in the resonator in a cycle of oscillation to the energy lost per radian of the cycle.

32. What are the features of microprocessor
Cost-effective: the microprocessor chips are available at low prices and results in its low cost.
Size: it is small size chip and hence portable.
Low power consumption: microprocessors are manufactured by using metaloxide semiconductor technology, which has low power consumption.
Versatility: the microprocessors are versatile as we can use the same chip in a number of applications by configuring the software program.
Reliability: the failure rate of IC in microprocessors is very low, hence it is reliable.

33. Explain differences between The Hlt and Hold States?
When HLT state is executed the processor stops functioning, buses go into tri state. No acknowledgment in any form is given by processor.
In the case of Hold, the processor goes into hold state but the buses are not driven to tri-state.
On other hands-on Hold, state processor gives out HLDA signal. This signal can be made to use by other devices.

34. Give an example of one address microprocessor?
8085 is a one address microprocessor.

35. Give examples for 8 / 16 / 32 bit Microprocessor?
8-bit Processor - 8085 / Z80 / 6800;
16-bit Processor - 8086 / 68000 / Z8000;
32-bit Processor - 80386 / 80486
