5.1.2
The cache mixes data and instructions and uses a 4-way set associative system. It is composed of
four ways (banks), each of which is divided into an address section and a data section. Each of the
address and data sections is divided into 128 entries. The data section of the entry is called a line.
Each line consists of 16 bytes (4 bytes
entries), with a total of 8 kbytes in the cache as a whole (4 ways). Figure 5.1 shows the cache
structure.
