Hi james

Thanx for ur reply

I downloaded ur custome instruction and as u suggest i did that thing.

Add in sopc and build again.

Ur custome instruction contain perl script and class.ptf.

Also i get the entry of ALT_CI_EXCEPTION_VECTOR 0x00000000 in system.h file but how to use this instruction in software and where?

If possible then can u give me some detail working of ur custome instruction..I already used tightly coupled memory.

when i ran the code i will not get any timing change in ISR..So is there any specific way to use ur custome instrucion?PLZ reply me SOON..waiting for ur reply.

Best Regards,
