17. Error Corrected Code Controller (ECCHRS)

Rev. 1.0.0.0

Features

Hardware Error Corrected Code Generation with two methods :

– Hamming code detection and correction by software (ECC-H)

– Reed-Solomon code detection by hardware, correction by hardware or software (ECC-RS)

Supports NAND Flash and SmartMedia devices with 8- or 16-bit data path for ECC-H, and with

8-bit data path for ECC-RS

Supports NAND Flash and SmartMedia with page sizes of 528, 1056, 2112, and 4224 bytes

(specified by software)

ECC_H supports :

– One bit correction per page of 512,1024,2048, or 4096 bytes

– One bit correction per sector of 512 bytes of data for a page size of 512, 1024, 2048, or 4096

– One bit correction per sector of 256 bytes of data for a page size of 512, 1024, 2048, or 4096

ECC_RS supports :

– 4 errors correction per sector of 512 bytes of data for a page size of 512, 1024, 2048, and

4096 bytes with 8-bit data path

Overview

NAND Flash and SmartMedia

devices contain by default invalid blocks which have one or

more invalid bits. Over the NAND Flash and SmartMedia lifetime, additional invalid blocks may

occur which can be detected and corrected by an Error Corrected Code (ECC).

The ECC Controller is a mechanism that encodes data in a manner that makes possible the

identification and correction of certain errors in data. The ECC controller is capable of single-bit

error correction and two-bit random detection when using the Hamming code (ECC-H) and up to

four symbols (a symbol is a 8-bit data) correction whatever the number of errors in symbol (1 to

8 bits of error) when using the Reed-Solomon code (ECC-RS).

When NAND Flash/SmartMedia have more than two erroneous bits when using the Hamming

code (ECC-H) or more than four bits in error when using the Reed-Solomon code (ECC-RS), the

data cannot be corrected.
