Control bus on Microprocessor in tamil

Control bus in Microprocessor. The width of the data bus is directly related to the largest number that the bus can carry, such as an 8 bit bus can represent 2 to the power of 8 unique values, this equates to the number 0 to 255.A 16 bit bus can carry 0 to 65535. Control bus – It is a group of conducting wires, which is used to generate timing and control signals to control all the associated peripherals, microprocessor uses control bus to process data, that is what to do with selected memory location. Some control signals are: Memory read Memory write I/O read I/O Write Opcode fetch If one line of control bus may be the read/write line.If the wire is low (no electricity flowing) then the memory is read, if the wire is high (electricity is flowing) then the memory is written.
