Hi!

Iam new to  dsp processors .............

Iam seeing the code for video encoder in bf533ez-kit lite........
Actually i don't know the assembly language programming.........

They have given the example code in assembly langauge.........
r0.l = _NHANDLER;
r0.h = _NHANDLER;  	// NMI Handler (Int2)

i know it is event handling of nmi interrupt...but where the _NHANDLER is defined...... what is
the significance............
where i can find the information...........

Please help............

thanx in adwance........

Hi,

_NHANDLER looks like a label for the entry point to the NMI handler.  You
can try a 'Find in files' search in VDSP++ with _NHANDLER as the search
parameter.  This should give you a number of options to look at in the
output window.

Best regards,
