It depends. From the CPU's point of view, 16 data lines are necessary in a 16-bit microprocessor. Some implementations, however, such as the 8088, use an 8-bit bus, instead of like the 8086, which uses a 16-bit bus. The Bus Interface Unit (BIU) handles the conversion, packing, and unpacking transparently to the Execution Unit (EU or CPU).

What is microprocesser 8085?
microprocessor 8085 is basic 8 bit microprocessor by Intel Corp. it has 64Kb memory and 16 address buses and 8 data buses it has 40 pin ic. 8 address and 8 data buses are multiplexed with each other for reducing the total number of pins from the microprocessor 8085 . it require 5MHz clock frequency for operation. only a crystal which connected easily across two pins of microprocessor can provide this clock.
Definition of Data Bus?
A communications bus which transfers information or data. Most busses are data busses. This can include the Front Side Bus, PCI bus, Memory Bus, and more.
What is 8085 mpu architecture?
8085 microprocessor is 8 bit microprocessor develop by Intel corp. it's architecture can be study broadly over internet various sites provide the information about architecture. some is given below 1-data bus - 8 2-address bus- 16 3-memory- 64 KB 4-GPRs - B,C D,E H,L 5-each of 8 bit 6- A L U. airthmatical logical unit.
What is the similarities between quantitative data and quantitative data?
don't you mean quantitative data and qualitative data?
Similarities between manual and computer database?
Both store data. Both will usually have some sort of structure and organisation to the data. The user of both can normally find the data they need. The user can normally derive the information they need from that data from both. The user can add data to both and remove data and change data.
How many Address lines and data lines of microprocessor and microcontroller?
Microprocessor has 16 address lines and microcontroller has 20 address lines
Why all the 16 address lines are not act as a data lines in 8085 microprocessor?
the 8085 microprocessor is a 8-bit microprocessor and these are bidirectional but the address lines are unidirectional.these address lines are used to address the location of the instruction in memory .these data lines are used to transfer data between processor and peripheral devices. when the address of the instruction will be recognized by the address lines the data will be send to the processor therefore the 16 address lines are not act as a data lines in 8085
What is the basic construction of microprocessor?
1)address lines to refer to the address of a block 2)data lines for data transfer 3)IC chips 4 processing data
What is DEN in 8086 in microprocessor?
Data enable, signals that bus lines are being used to transfer data
What are the basics of microprocessor?
1)address lines to refer to the address of a block 2)data lines for data transfer 3)IC chips 4 processing data
Consider two microprocessors having 8 and 16bit wide external data buses respectivelyThe two processors are identical other wise and their bus cycles take just as longsuppose all instructions?
During a single bus cycle, the 8-bit microprocessor transfers one byte while the 16-bit microprocessor transfers two bytes. The 16-bit microprocessor has twice the data transfer rate.
What is the real meaning of 16bit?
16bit refers to the number of bits that can be used in a single data format element. 16bit graphics are found in games that can be played on the original Nintendo Entertainment System console.
How many data lines in 8086?
There are eight datalines, D0 through D7, in the 8085 microprocessor. They are shared, or multiplexed with the eight low order address lines, A0 through A7, and are called AD0 through AD7 on the pinout drawing.
What is mean by address and data bus of 8086 microprocessor?
group of wires or lines that are used to transfer adress between microprocesssor and i/o devices one way and of 20 bits while data bus uses bothway transfer of data between microprocessor and i/o devices of 16 bits
What is the need for timing diagram in microprocessor?
The need for a timing diagram for a microprocessor is, primarily, to allow you to properly design the interface logic that will support the microprocessor. You need to know what lines are used to execute various data transfers, what are the timing of those lines with respect to each other, and how the microprocessor expects the external logic to behave. You can also use the timing diagram to understand how the microprocessor functions and, particularly, to know how long each instruction will take.
Why read and write control lines in a dma controller bidirectional?
The read and write control lines running through the data buses have control signals. The microprocessor can read data from memory or write data to the memory so the data buses are bidirectional. One direction is needed to write the data while another direction is required for the read command to fetch the data.
The system component that controls and manipulates data in order to produce information is called the?
microprocessor
