16 ECC (Error Correction Code)
16.1 Functional Description
The ECC (Error Correction Code) is used to correct data error in storage device or various kind of
communicating system. The TCC76x has a simple ECC generation module that calculate these ECC for this
purpose. By enable ECC module, it consistently monitors internal bus activity and calculate ECC whenever there
is read or write cycle from/to a predefined memory area. The area can be determined by special register so this
module can be used ECC calculation itself not only for specific storage device such as NAND flash.
The following figure represents block diagram including internal bus connection for ECC module.
