Imagine the difference that exists between a cache that is completely associative and one that is directly mapped.
Consider about the difference between a directly mapped cache and a totally associative cache.
Draw a line between a cache that is fully associative and one that is directly mapped out.
There is a cache with 8 blocks, find the number of misses for each cache organization (Direct-mapped, 2-way associative, 4-way associative) given the following sequence of block addresses: 10110, 11110, 10111, 10110, 11110, 10111 11110,10110,00011,10000,10010,10000
Keep in mind the difference between a fully associative cache and a directly mapped cache.
Make the difference between a cache that is directly mapped and one that is totally associative.
For a direct-mapped cache design with a 32-bit address, the following bits of the address areused to access the cache.Tag Index Offset31–10 9–6 5–0a– What is the cache block size (in words)? b – How many entries does the cache have? c – What is the ratio between total bits required for such a cache implementation overthe data storage bits?
Take into consideration the difference between a fully associative cache and a directly mapped cache.
A computer using direct mapping cache has 256Mbytes of byte addressable main memory and cache size of 32k lines and each cache block contain 8 bytes. How many blocks of main memory are there?What are the size of the tag, line number and words?To which cache block will the memory address 13ADEF9H map?To which line number will the memory address 17FEAD8H map?
Consider a cache with the following parameters: N (associativity) = 2, b (block size) = 2 words, W (word size) = 32 bits,C (cache size) = 32 K words, A (address size) = 32 bits. You need consider only word addresses.(a) Show the tag, set, block offset, and byte offset bits of the address. State how many bits are needed for each field.(b) What is the size of all the cache tags in bits?(c) Suppose each cache block also has a valid bit (V) and a dirty bit (D). What is the size of each cache set, including data, tag, and status bits?(d) Design the cache using the building blocks in Figure 8.28 and a small number of two-input logic gates. The cache design must include tag storage, data storage, address comparison, data output selection, and any other parts you feel are relevant. Note that the multiplexer and comparator blocks may be any size (n or p bits wide, respectively), but the SRAM blocks must be 16K × 4 bits. Be sure to include a neatly labeled block diagram. You need only design the…
