AM2431: Regarding TRM "8.1.4.3.1 ECC Cache", the contents of the ECC Cache for SDRAM are unknown.

?? ??

Part Number: AM2431

Tool/software:

The TRM refers to spruim2g.pdf.

Regarding TRM "8.1.4.3.1 ECC Cache", I do not understand the relationship between SDRAM and ECC Cache.

I would like to know the outline of ECC Cache for SDRAM.

Thank you in advance.

Hello ,

AM423X devices have cache memory.

So, when the CPU wants to read data from MSRAM/DDR they read from the cache to improve the read/write performance.

Similarly, DDR inline ECC bits are stored in the ECC cache. So, will read / write ECC bits instead of DDR reads from Cache to improve performance.

Anil.
