parallel assembly question

hi!

i'm looking for the fastest way to clear the Content of a Memory area.

so

[I++]=R0 in a Hardware Loop is possible

is there a faster way by using Two Parallel Memory Access Instructions ??

mnop || r1 = [i0++] || r3 = [i1++] ;
is possible

but [i0++]=r1 || [i1++]=r3 also ???

thanks and regards
