Cache Size ID Register
| LINESIZE | (Log2(Number of words in cache line)) - 2. 0 (LINESIZE_0): The line length of 4 words. 1 (LINESIZE_1): The line length of 8 words. 2 (LINESIZE_2): The line length of 16 words. 3 (LINESIZE_3): The line length of 32 words. 4 (LINESIZE_4): The line length of 64 words. 5 (LINESIZE_5): The line length of 128 words. 6 (LINESIZE_6): The line length of 256 words. 7 (LINESIZE_7): The line length of 512 words. |
| ASSOCIATIVITY | (Associativity of cache) - 1, therefore a value of 0 indicates an associativity of 1. The associativity does not have to be a power of 2. |
| NUMSETS | (Number of sets in cache) - 1, therefore a value of 0 indicates 1 set in the cache. The number of sets does not have to be a power of 2. |
| WA | Indicates whether the cache level supports write-allocation 0 (WA_0): Feature not supported 1 (WA_1): Feature supported |
| RA | Indicates whether the cache level supports read-allocation 0 (RA_0): Feature not supported 1 (RA_1): Feature supported |
| WB | Indicates whether the cache level supports write-back 0 (WB_0): Feature not supported 1 (WB_1): Feature supported |
| WT | Indicates whether the cache level supports write-through 0 (WT_0): Feature not supported 1 (WT_1): Feature supported |
