1) Given a virtual memory system with: virtual address 36 bits physical address 32 bits 32KB pages (15 bit page offset) Each page table entry has bits for valid, execute, read and dirty (4 bits total) and bits for a physical page number. a) How many bits in the page table? (do not answer in bytes!) Three digit accuracy is good enough. The exponent may be either a power of 2 or a power of 10. b) The virtual address...

36.-Assume a 32 bit memory space with 16[KB] pages/frames and a two-level page table. Answer the following questions: a).-what is the size of the page table in bytes needed for a process that has only 64[MB] of code at the start of its virtual address range? b).-how many bits are used for address (frame) offset, and how many for page table indexing (total). Assume each page table entry has 32 bits. a).-Size of page table b).-Offset bits b).-Page table indexing...

A primary memory system consists of 128 address bits. Each block within the cache is 256 bytes. The total cache size is 131,072 bytes. What are the sizes of the tag and index in the cache? First, find the number of blocks. 128,000 bytes # Blocks = 256 bytes per block bort = 512 blocks Where does the 128,000 come from?? Now find the number of bits required to distinguish all the blocks. This is the index aka set size....

Suppose a machine does not use a multi-level page table. Suppose further, that the system uses a 54-bit virtual address and a 30-bit physical address. If the page size is 16K, how many entries should you have in the page table? You may express the answer as a power of 2. (1) Is the decision to have a single level page table a reasonable one? Explain (2) If you are to use the inverted page table in this system, what...

A certain byte-addressable computer system has 32-bit words, a virtual address space of 4GB, and a physical address space of 1GB. The page size for this system is 4 KB. Assume each entry in the page table is rounded up to 4 bytes. a) Compute the size of the page table in bytes. b) Assume this virtual memory system is implemented with a 4-way set associative TLB (Translation Lookaside Buffer) with a total of 256 address translations. Compute the size...
