2.3.1
The PIC32MX3XX/4XX family core provides a simple
Fixed Mapping Translation (FMT) mechanism that is
smaller and simpler than a full Translation Lookaside
Buffer (TLB) found in other MIPS cores. Like a TLB, the
FMT performs virtual-to-physical address translation
and provides attributes for the different segments.
Those segments that are unmapped in a TLB
implementation (kseg0 and kseg1) are translated
identically by the FMT. Figure 2-3 shows how the FMT
is implemented in the PIC32MX core.
FIGURE 2-3:
In general, the FMT also determines the cacheability of
each segment. These attributes are controlled via bits
in the Config register. Table 2-4 shows the encoding for
the K23 (bits 30:28), KU (bits 27:25), and K0 (bits 2:0)
fields of the Config register. The PIC32MX core passes
these Config fields to the Prefetch Cache module to
determine cacheability of Program Memory Flash
accesses. Table 2-5 shows how the cacheability of the
virtual address segments is controlled by these fields.
