This machine has separate caches for data and instructions, where the size of the data cache is 64KB with 128-bytes cache lines.
Through hardware assist, the entire tablewalk routine fits in two cache lines of memory and provides a low-cost, flexible, and fairly fast TLB reload capability.
Namely, a relationship like (j mod 4) = 0 summarizes, that, in a sequence of unit-stride accesses in which four data elements fit on a cache line, every fourth access will result in a cold miss.
This can still improve time because the entire compressed array now fits into a cache line and the search (linear or binary) is done with processor registers [Degermark et al.
For array-based codes, a useful dynamic context would distinguish the first loop iteration from the remaining iterations (to capture temporal locality), and the loop iteration modulo the cache line size (to capture spatial locality).
6) Note that this model only captures true communication and does not attempt to predict coherence missed due to the false sharing of separate items within the same cache line [Eggers and Jeremiassen 1991; Torellas et al.
This eviction accesses one extra cache line for the empty overflow buffer entry into which the evicted entry is written.

Other performance enhancing features include a full PCI bandwidth large burst transfer capability that allows data bursts of up to 256 words to be transferred at full PCI bus speed, and the capability to automatically convert a PCI Read command to a Read Multiple command and when possible, read an entire cache line from memory.
