Question 16 Suppose we have a virtual address space of 8 kilobytes (KB), a physical memory size of 6 kilobytes (KB) that uses byte addressing, and a page. size of 3 kilobytes (KB). There is no cache in the system. What are the sizes of the page and offset fields in the virtual address? a. page field; 3 bits and offset field: 10 bits b. page field: 2 bits and offset field: 11 bits c page field: 10 bits and offset field: 3 bits d. page field: 8 bits and offset field: 4 bits e. None of the other answers.
Suppose a computer system uses 16-bit addresses for both its virtual and physical addresses. In addition, assume each page (and frame) has size 256 bytes. Could you hand draw the page table, if possible a) Suppose that the OS uses a two-level page table. Draw the page table. (Assume that frames 7 through 221 are free, so you can allocate space for the page table there.) In addition, suppose that the page-table directory storage comprises a whole number of consecutive full frames. (For examples: if the directory entry is 2 bytes, the entry’s storage comprises 1 frame; if the directory entry is 260 bytes, the entry’s storage comprises 2 consecutive frames.) b) What is the size of the two-level page table

4. Suppose a computer using a fully associative cache has 2^24 byte of byte-addressable main memory and a cache of 128 blocks, where each block contains 64 bytes. a) How big in kilobytes is main memory? b) How big in bytes is cache? In kilobytes? c) How many blocks of main memory are there? d) What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag and offset fields? e) To which cache block will the memory address 0x01D8729A map?
Q.2 Suppose a system has a logical address space of size 25 (m=5), a page size of 4 bytes, and a physical memory of 128 bytes.
