Given information:
Clock frequency of 8085 microprocessor = 5 MHz
Time required to execute an instruction = 1.4 s
To find: Number of T-states needed for executing the instruction
Explanation:
T-states are the number of clock cycles required to execute an instruction. The number of T-states depends on the type of instruction being executed.
The 8085 microprocessor has a 1-byte instruction set, which means that each instruction is 1 byte long. The time taken to execute an instruction depends on the number of T-states required to execute that instruction.
The formula to calculate the time taken to execute an instruction is:
Time taken = (Number of T-states / Clock frequency)
Given that the clock frequency of the 8085 microprocessor is 5 MHz, we can calculate the number of T-states required to execute an instruction as follows:
Number of T-states = (Time taken x Clock frequency)
Number of T-states = (1.4 x 10^-6 s x 5 x 10^6 Hz)
Number of T-states = 7
Therefore, the number of T-states needed for executing the instruction is 7.
