Error code correction (ECC)
Over the product lifetime, and/or due to external events such as radiations, invalid bits in
memories may occur. They can be detected and corrected by ECC. This is an expected
behavior that has to be managed at final-application software level in order to ensure data
integrity through ECC algorithms implementation.
SRAM data are protected by ECC:
•
7 ECC bits are added per 32-bit word.
•
8 ECC bits are added per 64-bit word for AXI-SRAM and ITCM-RAM.
The ECC mechanism is based on the SECDED algorithm. It supports single-error correction
and double-error detection.
