8.3.1.5.2 Error Correction Logic

The Error Correction Logic generates the ECC code for SRAM reads and writes. For

reads, this logic compares the ECC codes read with the locally generated ECC code. If

the codes mismatch then the Error Correction Logic determines the error type. For a

single-bit error, this block determines which bit is in error and corrects the error. For a

single-bit or multi-bit error, the Error Correction Logic logs the error in ELOG0 and

ELOG1. See

Section 8.3.3, “Error Correction and Detection” on page 519

for more

details.
