How does a microprocessor know whether the next byte is an instruction or data?
A microprocessor know whether the next byte is an instruction or data because the microprocessor knows for what it is looking. The bus, on the other hand, for an 8085 based system, knows an opcode from data by looking at S0 and S1 when IO/M- is low. If both are high, it is an opcode, otherwise it is data.
Where is microprocessor placed in computer?
The central processor unit (microprocessor) is placed on the motherboard. The cooler, necessary to refrigerate the microprocessor is placed behind it.
What is a 8085 microprocessor?
The 8085 microprocessor is an 8-bit microprocessor introduced by Intel in 1976. It is a popular microprocessor used in many early computer systems and embedded devices. The 8085 has a 16-bit address bus and an 8-bit data bus, with a clock speed ranging from 2 to 3 MHz. It has a total of 74 instructions in its instruction set architecture.
What is the role of clock generator in microprocessor?
The clock signal in a microprocessor allows synchronization of several components of the microprocessor. The correctness of the computation of the microprocessor depends upon efficient and balanced distribution of the clock signal. The clock generator generates the clock signal.
Who is Marician Hoff?
hi bye i hate yo! Marcian Hoff was one of the inventors for the microprocessor. The microprocessor is like the engine for the computer. When you turn on the computer the microprocessor helps the computer start.
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.
What do you mean by AD bus in microprocessor?
ad is multiplex address data line 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
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?
32 bit
Why 2 gnd are used in microprocessor 8086?
Two ground pins are used in the 8086 microprocessor to increase the bus pull-down current capacity.
