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
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.
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 type of ram is synchronized to the microprocessor's memory bus?
RIMM
Consider a 16 bit microprocessor with a 16 bit external data bus driven by an 8 bit MHz input cycleswhat is maximum data transfer rate across the bus that this microprocessor can sustain?
Minimum bus cycle duration = 4 clock cycles Bus clock = 8 MHz Maximum bus cycle rate = 8 M / 4 = 2 M /s Data transferred per bus cycle = 16 bit = 2 bytes Data transfer rate (per second) = Bus cycle rate * data per cycle = 2 M * 2 = 4 M bytes per second
What is meant by latching in microprocessors?
It is the time period in the clock cycle in which the signal on the bus must be the valid expected data. ie. The stable period of the data transmission that will then be loaded into the microprocessor as the actual data.
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 a 8085 microprocessor?
with neat diagram explain the system bus structure of 8085
If bus clock rate is 250MHz what is duration of each bus cycle?
Cva:As bus cycle is not mentioned, hence assumed that bus cycle = clock rate = 250MHz.Duration of each bus cycle = 1 / 250M = 4ns; Please, correct me if I am wrong.
