Why do we use byte addressing instead of word addressing?

The basic unit of digital storage is a bit, storing a single 0 or 1. Many common instruction set architectures can address more than 8 bits of data at a time. For example, 32-bit x86 processors have 32-bit general-purpose registers and can handle 32-bit (4-byte) data in single instructions. However, data in memory may be of various lengths. Instruction sets that support byte addressing supports accessing data in units that are narrower than the word length. An eight-bit processor l… WebThe cache set indexCT. The cache tag. Suppose we have a system with the following properties:The memory is byte addressable.Memory accesses are to 1-byte words (not to 4-byte words).Addresses are 13 bits wide.The cache is 4-way set associative (E = 4), with a 4-byte block size (B = 4) and eight sets (S = 8).Consider the following cache state.
