9. In a paging system , the logical address is formed of 20 bits. the most significant 8 bits denote the page number, the least significant 12 bits denote the offset. Memory size is 256K bits.
a. What is the page size (in bits)?
b. What is the maximum number of pages per process?
c. How many frames does this system have? d
. Give the structure of the page table of a process executing in this system. Assume 2 bits are reserved for attributes.
e. How many bits are required for each page table entry?
f. If physical memory is upgraded to 1024 K bits, how will your answer to c and e change?

- A 2-way set associative cache consists of four sets. Main memory contains 2K blocks of eight words each. Show the main memory address format that allows us to map addresses from main memory to cache. Be sure to include the fields as well as their sizes. Compute the hit ratio for a program that loops 6 times from locations 8 to 51 in main memory. You may leave the hit ratio in terms of a fraction. Please show details how you obtain the result.arrow_forwardQ.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. Given the following page table, find out the respective physical addresses for each of the logical address listed in Table 2. (Note: all addresses are expressed in decimal number system) Table 1: Page table 0 2 5 7 0 15 1 2 3 4 5 18 6 20 7 22 Table 2: Fill out this table with corresponding physical memory addresses Logical Address Physical Address 0 6 10 17 23arrow_forwardLet's double the size of the address field from 32b to 64b.
