An explanation of dynamic memory allocation in the simplest terms possible
Problem 0. The following table gives some of the parameters for a number of different hardware caches. Fill in the table with the values of the missing parameters. Recall that m is the number of physical address bits, C is the cache size in bytes, B is the block size in bytes, E is the associativity, i.e., lines per set, S is the number of sets, t is the number of tag bits, s is the number of set index bits, and b is the number of block offset bits.

Suppose a byte-addressable computer using set associative cache has 224 bytes of main memory and a cache size of 64K bytes, and each cache block contains 32 bytes. a) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, set, and offset fields? b) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?

This is essentially the gist of the explanation for dynamic memory allocation.
A memory system has 4 KB byte-addressable main memory and a direct-mapped cache that consists of 8 blocks with 16 bytes per block. The following shows the main memory address format that allows us to map addresses from main memory to cache. Note: 12 bit address, 4 bit offset, 3 bit $block, and 5 bit tag Assume the cache directory shown below:
Suppose a computer using direct-mapped cache has 2 bytes of byte-addressable main memory and a cache of 32 blocks, where each cache block contains 16 bytes.Q.) What is the format of a memory address as seen by the cache; that is, what are the sizes of the tag, block, and offset fields?
