Why 8085 microprocessor's AD BUS go into high impedence state before switching as a data data bus?
The 8085 microprocessor's AD bus goes into high impedance state before switching as a data input bus because you don't want two bus drivers driving the bus at the same time. You give the bus time to float between transfer of control, otherwise there will be large power transients at switchover, and you could damage the drivers.
What is an address bus in a microprocessor?
The address bus is a section of the bus that emits the address of the desired instruction or operand.
What is known as 8 bit internal bus?
the bus through which the data are transmitted or received within microprocessor and with peripherals is called as data bus.when used internally to microprocessor called internal data bus.
Why is data bus bidirectional but address bus is unidirectional?
since data can be read /write from/to the microprocessor, hence data bus is bidirectional. if data is required read from microprocessor then it will be pointing to a memory location by the address bus, by indicating which location data its required to read. similarly to write a data to a location, again the microprocessor will be to that particular location by holding that address in address bus. hence it will be unidirectional.
What is bus cycle in a microprocessor?
Bus cycle is a single transaction between the main memory and the CPU.
What type of ram is synchronized to the microprocessor's memory bus?
RIMM
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
Role of latches in 8086 microprocessor?
for demultiplexing address/data bus
What is the data path beween the microprocessor RAM and the peripherals?
Data bus
What is the function of control bus in references to 8085 microprocessor?
It provides timing signals.
what is the communication path between a microprocessor ram and peripherals called?
The data bus.
What is the width of the address bus on the modern core i7 microprocessor?
