Add Block-CRC verification acceleration support ????

[Altera_Forum]

Hallo 

 In the PFL IP core settings there is this option to to turn or Add Block-CRC verification acceleration support. The description says ''adds a block to accelerate verification (only available if you choose CFI parallel Flash) "".   What is the advantage of having this block turned on or off? If i turn it off, does it affect the performance in a way?

Hi, 

 By default, CRC option is enabled. Which protect against common types of errors on communication channels. If CRC option is disabled, we can still program flash but we may face data corruption which can be detected during operation.  Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)

Hallo 

 Thanks a lot for your reply. I was just concerned because turning on/off the block makes a change in the number of L,E used. And when i turn off this option i just found out that i could use a smaller MAX device with lower L.E count just to reduce the cost, but after your reply it looks like, to keep the block turned on and use a bigger MAX device is a better idea.  Sorry for the late reply, for some reason, i didn't get a e-mail notification of your answer.

How much were you able to reduce the cost for btw, Shauk? That's very interesting.
