A UNIX-type file-system uses a disk block size of 1KB, 128 byte inodes, and 32 bit disk addresses. If the inode contains 64 bytes of data, 8 direct, 1 indirect, 1 double-indirect, and 1 triple- indirect blocks, apart from other file information. How many disk blocks would be required for storing files of sizes (a) 1 byte (b) 1024 bytes (c) 64 KB (d) 1MB ?
A machine has a 16-bit byte-addressable virtual address space. The page size is 8 KB. How many pages of virtual address space exist? (25 points)
1. A character in a ASCII system has size 1 byte or 8 bit (1 or 0) A). How many bit patterns are formed? B). How many bit patterns have 3 bits 1? C). How many bit patterns have an even number of bits 1?
A (word, bit, block, byte) or (Sector, cache line, page, row) is the unit of data transferred between cache, memory and the processor. A common size for a block is (64, 16, 32, 4k, 512) (bytes, lines, words, bits)
Four 8-bit 2's complement (signed) integers A, B, C, and D are packed into the 32-bit word stored in the memory of an ARM processor at address 0x36F0: Extract the 8-bit integer A into the 32-bit register Ra, the 8-bit register B into the 32-bit register Rb,the 8-bit register C into the 32-bit register Rc, and the 8-bit register D into the 32-bit register Rd. Hint: in ARM an address refers to a byte, not a word
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. What is the total size of the page table for each process on this processor, assuming that the valid, protection, dirty, and use bits take a total of 4 bits and...
A computer with a 24‐bit address bus has a main memory of size 16 MB and a cache size of 64 KB. The word length is two bytes. a. What is the address format for a direct mapped cache with a line size of 32 words? b. What is the address format for a fully associative cache with a line size of 32 words? c. What is the address format for a 4‐way set associative cache with a line size...
Memory Sizing NOTE: K (kilo) means 1024, not 1000. A byte (B) is 8 bits. A kilobyte (KB) is therefore 8 x 1024 = 8192 bits. a) A 32 KB (kilobytes) memory has a 16 bit wordsize. How many words total can be stored in this memory? _________words b) A 256 KB memory has a 32 bit wordsize. How many bits are required to address this memory? _________ bits c) A computer memory has a 128 bit wordsize. It is made up...
) Consider an 8-way associative 64 Kilo Byte cache with 32 byte cache lines. Assume memory addresses are 32 bits long. a). Show how a 32-bit address is used to access the cache (show how many bits for Tag, Index and Byte offset). b). Calculate the total number of bits needed for this cache including tag bits, valid bits and data c). Translate the following addresses (in hex) to cache set number, byte number and tag (i) B2FE3053hex (ii) FFFFA04Ehex...
