Question 2. [7] The Motorola 68000 microprocessor is byte addressable with a 24-bit address bus and a 16 bit data bus, and one word contains 2 bytes. Your manager wants to purchase RAM chips each containing IM words, where each word is 2 bytes, for a total of 220words (equivalent to 22 bytes) (a)(1]What is the maximum number of these RAM chips you could place in your system and be able to address? (b)131 Having decided how much RAM could be bought, your manager realizes that the whole address space has been used up for it, leaving no room for peripherals to make the system useful after all. The manager tells you to buy half as much RAM as what was calculated above and use the rest of the address space to install peripherals. They would like to have a beast 32 peripherals each of which is byte addressable and requires an address space of 64KB. Your mainager asks you to check that it is all feasible.. Is it? YES NO (circle one) Show a complete logical explanation of the reasoning for your answer, as you might do at work (c)If the answer above stated that 32 peripherals is too many, state how many you could handle in your system, without reducing further the RAM. (d)If the answer above stated that 32 peripherals fit exactly into the address space, then you are finished. (e)If the answer above stated that you could fit 32 peripherals and you had spare address space, state how much more RAM you could have in your system (that is, how many more chips you could buy. Choose one of the three cases (c), (d) or (e) and give an answer with explanation. [3]
