associativity ubyte associativity;

Number of ways of associativity, eg:

1 = direct mapped
2 = 2-way set associative
3 = 3-way set associative
ubyte.max = fully associative

lineSize uint lineSize;

Number of bytes read into the cache when a cache miss occurs.

size size_t size;

Size of the cache, in kilobytes, per CPU. For L1 unified (data + code) caches, this size is half the physical size. (we don't halve it for larger sizes, since normally data size is much greater than code size for critical loops).
