A $5-$ stage pipelined processor has IF,ID,EX,MEM and WB . WB stage operation is divided into two parts. In the first part register write operation and in second part register read operation is performed. The latency of those stages are $300,400,500,500,300$ (in nano seconds) respectively.Consider ... $I_{4}$ SUB $R_{1},R_{7},R_{4}$ $R_{1} <- R_{7} - R_{4}$ The program execution time__________ns?
