P2. For a synchronous read operation, the memory module must place the data on the bus sufficiently ahead of the falling edge of the Read signal to allow for signal settling. Assume a microprocessor bus frequency is 10 MHz and the Read signal begins to fall in the middle of the second half of T3. a. Determine the length of the memory read instruction cycle. Hint: How many clock cycles does a read instruction need? b. When, at least, should the memory data be placed on the bus? Allow 20 ns (1 ns = 10-9s) for the settling of data signal.
