Q2. (4 pts) A certain microprocessor (uP) has a 37-bit address bus and a 32-bit wide data bus. Here, similar to Q1, we are using byte packing, that is, we should be able to access each byte in the memory. Assume that you are using a memory chips organized as 128K by 8 bits. Q2-1.Divide the 37-bit address lines into page number bits, offset bits and byte address bits. Q2-2.How many 128K by 8 memory devices would you need to...
Problem #1 (25 points) Address Space, Memory Consider a hypothetical 18-bit processor called HYP18 with all registers, including PC and SP, being 18 bits long. The smallest addressable unit in memory is an 8-bit byte. A. (4 points) What is the size of HYP18's address space in bytes and KB? How many address lines does HYP18 require? Address space: Bytes Address space: KB (KiloBytes). Address bus lines: B. (6 points) Assume that first quarter of the address space is dedicated...
Suppose that we have a computer system using 32-bit logical address and 46–bit physical address. It also uses paging for memory management with a single-level page table organization. The page size is 4K bytes and each page table entry is 32 bits or 4 bytes in size. Calculate the number of bits in each field in the logical address, the size in bytes of the page table, and the number of frames.
Question 3. A computer has a memory space of 16 GB. a) How many address lines are required to span this address space, assuming it is byte- addressed? b) This computer has a block of 4 GB 32-bit-wide memory built using 512 MB static RAM chips that are each 8 bits wide. How many RAM chips are required to implement the memory?
Consider a virtual memory system with the following properties: 36 bit virtual byte address, 8 KB pages size, and 32 bit physical byte address. Please explain how you determined your answer. a. What is the size of main memory for this system if all addressable frames are used? b.

Consider 512Kx8bits dynamic RAM chips where the memory access time is 2/3 of the memory cycle time. These chips have an Address Bus, a bi-directional Data Bus, a Read/Write control line and a Chip Select line. (a) Draw the diagram of a memory organization that will contain 4 megabytes, will have a 32-bit bi-directional data bus and will yield one word (32-bits) every access time if words are read from consecutive memory locations (in bursts).
