since valid bits is not specified,it is not counted. Orelse valid bits are also counted as overhead
please upvote... I need it.. Thanks
Given a direct-mapped cache that will contain 32,768 bytes of data and four-word blocks (where each...
A direct- mapped cache holds 1024 (or 2^10) blocks where each block is 1 word. What is the actual size of one entry in the cache in bits? Assume the address is 32 bits. Include the valid bit and dirty bits in the calculation. 32 54 52 22
a) Suppose we have a 64 KB, direct-mapped cache with 8-word blocks. Determine how many bits are required for the tag, index, and offset fields for a 32-bit memory address. b) If instead, we use a 64 KB, 4-way set-associative cache with 8-word blocks, how many bits will be required for the tag, index, and offset fields for a 32-bit address? c) What type of cache is shown in problem 2? How many bits are required for this cache’s tag,...
A direct-mapped cache has 4 blocks and each block holds four bytes of data. The memory system is byte-addressable. Determine if each of the memory references below is a hit (H) or miss (M).

For a 16K-byte, direct-mapped cache, suppose the block size is 32 bytes, draw a cache diagram. Indicate the block size, number of blocks, and address field decomposition (block offset, index, and tag bit width) assuming a 32-bit memory address.

Consider a direct-mapped cache with 32 blocks Cache is initially empty, Block size = 16 bytes The following memory addresses (in hexadecimal) are referenced: 0x2B4, 0x2B8, 0x2BC, 0x3E8, 0x3EC,0x4F0, 0x8F4, 0x8F8, 0x8FC. Map addresses to cache blocks and indicate whether hit or miss
Assume a cache with 2048 blocks, a 4-word block size, and a 32-bit address. For each of the following configurations, find the total number of bits for each cache block and the total numbers of bits for the entire cache. a. Direct-mapped b. Two-way set associative c. Four-way set associative d. Fully-associative
Assuming a direct-mapped cache with 4 four-word
blocks that is initially empty, label each reference in
the list as a hit or a miss and show the final contents of the
cache.
The following is a sequence of address references given as word
addresses.
