Best Answer

The 8086/8088 has a clock oscillator circuit. You provide a crystal, and it will generate a clock signal that controls the speed of the processor. In that respect, it has a clock.

The 8086/8088, however, does not have a time of day or date clock. You can build a software entity that keeps day/date time using interrupts from a divider off of the clock oscillator but, that is not the same thing as a non-volatile clock chip such as provided in the PC, but which is not part of the 8086/8088.

How clock signal are generated in 8085 and what is the frequency of the internal clock?

Early microprocessor neded clock input to be given externally, i.e. an extra clock generator chip is necessary. the clock generator chip had two pins between which a crstal or an RC circuit could be connected for the generation of basic frequency desired. however, microprocessor, that were designed after 1978(Intel 8085, M6809, etc.) had the clock generator circuit embedded in the microprocesor chip.


How many instructions execute in one second in 8086 microprocessor?

The number of instructions that can execute in one second in the 8086 microprocessor is highly dependent on clock speed, memory wait time, and instruction complexity mix, but the generally accepted performance factor is 0.33 MIPS (Million Instuctions per Second) at a clock speed of 4.77 MHz.

How the speed of 8086 microprocessor can be increased?

To increase the speed of the 8086, you need to increase the clock speed, reduce the number of wait states, or both. You could also optimize your code so that it runs faster. Since the 8086 is a segmented memory architecture, it is more efficient to use operands in one segment and to make near references to them.


What is the difference between 8086 and 8088 microprocessor?

The difference between the 8086 and the 8088 is that the 8086 has a 16 bit data bus and that the 8088 has an 8 bit data bus. Both processors are the same 16 bit processor, and both have a 20 bit address bus. The 8086 is twice as fast as the 8088 in terms of data transfer rate on the bus for the same bus clock speed.
