4.7 Logical to Physical Table
Figure 4-7. Logical to Physical Address Translation Table
Figure 4-7
shows the logical to physical translation table. It reads the ExtraDataArea of physical block of
the NAND Flash to retrieve the logical address and store to the table. For high speed processing, it is
desirable to construct a table of alternate blocks, as well as the logical/physical translation table. In this
firmware, the RAM block 0 is to store the conversion table for the physical segment 0 of the NAND Flash,
which is to store boot record, FAT table and directories content. The RAM block 1 is to store the
conversion tables for the physical segment 1 to 3 of the NAND Flash for the file data content.
