TMS570LS3137: ECC Encoding Algorithm in TMSx70

Ktmn

Hello,

1) "ECC Encoding" is explained in "Table-1" in the "1.5- Error Correcting Code (ECC)" section of the "ECC Handling in TMSx70-Based Microcontrollers" document that I used as a source.

But I could not fully understand the ECC algorithm.

As far as I understand, we process the data in the "X" marked places in this table with the "XOR" operator. But I did not understand the logic and operation of this. I couldn't figure out how it would work for other address, MSW or LSW values.

Can someone explain this for "beginners"? How is the mathematical model or operation of this?

2) Another question is, are the "ECC" values unique values or can they get the same value again?

3) When I researched, they basically stated that I had to process the data data with the XOR operator, but when I tried the examples in the document, I could not reach the same result. Is there a possibility that there is a problem with the document? Could you please explain step by step calculating ECC with an example?
