`s1/l1/a1`	Defines level 1 cache properties
`s1/l1/a1:s2/l2/a2`	Defines level 1 and 2 cache properties.
`s1/l1/a1:s2/l2/a2:s3/l3/a3`	Defines level 1, 2, and 3 cache properties

The definitions of the cache properties, si/li/ai, are as follows:

`si`	The size of the data cache at level `i`, in kilobytes
`li`	The line size of the data cache at level `i`, in bytes
`ai`	The associativity of the data cache at level `i`

For example, i=1 designates level 1 cache properties, s1/l1/a1.
