Design a parallel-input parallel-output (PIPO) 3-bit Register using D-flipflops. The register has twoinput lines for operation selection. Based on the values of the input lines, the register can perform thefollowing four operations00 – Shift Right01 – Shift Left10 – Decrement (-1)11 – Increment (+2)
An input I/O device has a polled status register and a data register. The status register is set to one to indicate that input data is ready. Using typical assembly-like code, write a polling routine that transfers each bye of input data to a processor register. If instructions are executed in 500 ns each, calculate the maximum rate at which data could be transferred over this interface.
