Memory Differences
1-13 Comparison of the ’C80 and the ’C82
1.5.3 Caches
Generally, cache operation is completely transparent; in most
cases you need not worry about cache differences between the
’C80 and the ’C82.
Cache memory is generally not directly accessed by application
software, so the locations of the caches are not important. This
information is available on the memory maps in Appendix A, for
your reference.
Table 1–2 lists the sizes of the caches in the ’C80 and ’C82. Bet-
ter PP performance may occur in the ’C82, since each ’C82 PP
instruction cache is twice as large as its corresponding ’C80 PP
instruction cache.
