Falcon ECC Memory Controller Chip Set

ECC Codes
When the Falcon reports a single-bit error, software can use the syndrome
that was logged by the Falcon (upper or lower depending where the error
occurred) to determine which bit was in error. Table shows the syndrome
for each possible single bit error. Table 3-23 shows the same information
ordered by syndrome. In order to relate this information to PowerPC
addresses and bit numbers, the user needs to understand how the Falcon
pair positions PowerPC data in DRAM. See the section on Data Paths on
page 3-64 for an explanation of this.
Note Table and Table 3-23 are the same whether the Falcon is
configured as upper or as lower.
