66AK2E05: PA EMAC Slow ISR handling?

Part Number: 66AK2E05

hi !!

okay so i have the following system

66AK2E05 (ARM CORES ONLY)


EVM <=> PC

running PA_EMAC example on K2e

all required work like loopback_none etc done

i have disabled L3, ALE etc, check is on MAC only

now i have a packet generator sending UDP packets over wire at max link speed, i.e. greater then at least 600Mb/s, now i am able to receive all packets as stated by the PA stats but only about 4 packets are verified which means that the ISR is slow and unable to handle higher speeds.

I also have a secondary application which exactly replicates PA_EMAC but in bare-metal which has a higher accumulator buffer size but is still not able to handle high data rates. (better then PA_EMAC example)

so my question is that is it possible to achieve max link speed on 1 core and if i have to implement multi core is there an example in which this has been done?

regards,

Hannan
