Combine simplified Microprocessor Unit, RAM 1 & 2, ROM, and I/O ports using appropriate hardware interface in order to achieve the memory map indicated.
ROM: 0000 - 07FF
RAM 1: 1200 - 13FF
RAM 2: 5000 - 50FF
I/O: E110 - E11F
The following hardware interface can be used to achieve the memory map indicated:
1. A multiplexer connected to the address bus of the microprocessor unit. The select inputs of the multiplexer can be connected to control signals generated by the microprocessor unit to select different memory spaces.
2. A decoder connected to the output of the multiplexer. The decoder can decode the address lines to generate chip select signals for different memory locations.
3. ROM chip connected to the output of the decoder. The chip select signal generated by the decoder will enable the ROM to respond to the microprocessor unit during the memory access cycle.
4. RAM 1 chip connected to the output of the decoder. The chip select signal generated by the decoder will enable the RAM 1 to respond to the microprocessor unit during the memory access cycle.
5. RAM 2 chip connected to the output of the decoder. The chip select signal generated by the decoder will enable the RAM 2 to respond to the microprocessor unit during the memory access cycle.
6. I/O ports connected to the output of the decoder. The chip select signal generated by the decoder will enable the I/O ports to respond to the microprocessor unit during the I/O access cycle.
The memory map can be achieved as follows:
ROM: 0000 - 07FF --> Connected to the decoder through the multiplexer, using the address lines A0-A10.
RAM 1: 1200 - 13FF --> Connected to the decoder through the multiplexer, using the address lines A0-A10.
RAM 2: 5000 - 50FF --> Connected to the decoder through the multiplexer, using the address lines A0-A10.
I/O: E110 - E11F --> Connected to the decoder through the multiplexer, using the address lines A0-A15.
With this hardware interface, the microprocessor unit can access different memory locations depending on the memory space selected. The ROM, RAM 1, RAM 2, and I/O ports are mapped to different address ranges, and the decoder generates chip select signals to enable each memory location during the memory access cycle.

To achieve the memory map indicated, you can use appropriate hardware interfaces to connect the microprocessor unit (MPU) with the various memory components and I/O ports. Here's a step-by-step guide on how you can achieve this:
1. Start by connecting the ROM to the MPU:
- Connect the address lines A0 to A10 of the MPU to the address inputs of the ROM.
- Connect the data lines D0 to D7 of the MPU to the data inputs and outputs of the ROM.
2. Connect RAM 1 to the MPU:
- Connect the address lines A0 to A9 of the MPU to the address inputs of RAM 1.
- Connect the data lines D0 to D7 of the MPU to the data inputs and outputs of RAM 1.
3. Connect RAM 2 to the MPU:
- Connect the address lines A0 to A7 of the MPU to the address inputs of RAM 2.
- Connect the data lines D0 to D7 of the MPU to the data inputs and outputs of RAM 2.
4. Connect the I/O ports to the MPU:
- Connect the address lines A0 to A4 of the MPU to the address inputs of the I/O ports.
- Connect the data lines D0 to D7 of the MPU to the data inputs and outputs of the I/O ports.
5. Set the base addresses for each component according to the memory map:
- Set the base address for ROM as 0000.
- Set the base address for RAM 1 as 1200.
- Set the base address for RAM 2 as 5000.
- Set the base address for I/O ports as E110.
By following these steps and appropriately connecting the components with the MPU using hardware interfaces, you can achieve the desired memory map indicated.
To achieve the memory map indicated, you will need to connect the different components using appropriate hardware interfaces. Here's what you need to do:
1. Start by connecting the microprocessor unit (MPU) to the memory components and the I/O ports. The MPU is responsible for processing instructions and data.
2. Connect the ROM module to the MPU. The ROM covers the memory range from 0000 to 07FF. Make sure to use the appropriate address lines and data lines to establish the connection.
3. Connect RAM 1 to the MPU. RAM 1 should cover the memory range from 1200 to 13FF. Again, use the necessary address and data lines to interface the MPU with RAM 1.
4. Connect RAM 2 to the MPU. RAM 2 should cover the memory range from 5000 to 50FF. Follow the same procedure as connecting RAM 1 to interface RAM 2 with the MPU.
5. Finally, connect the I/O ports to the MPU. The I/O ports should cover the memory range from E110 to E11F. These ports allow the MPU to communicate with external devices. Ensure that the appropriate address and data lines are connected to establish communication.
By properly connecting the components using the appropriate hardware interfaces, you will achieve the desired memory map indicated by the ROM, RAM 1, RAM 2, and I/O ports addresses.
