Question: a. A processor has 24 bits in the external address bus. The word length of the bus is 8 bits. The device with the processor

a. A processor has 24 bits in the external address bus. The word length of the bus is 8 bits. The device with the processor has 2 MB Flash memory, 1 MB static RAM and 256 kB EEPROM. In addition 6 MB is reserved for flash expansion, 3 MB for RAM expansion and 2 MB is reserved for unspecified memory expansion. How much can the EEPROM be extended?

b. The processor of the previous exercise sets PC to address 0 at reset. Sketch a memory map for the processor. Memory map must show start and end address of each memory type in a table.

c. Computer has 4 gigabytes of memory and bus width is 32 bits. Memory is constructed using 128 M x 8 memory chips. How many chips are needed and how they should be organized?
