memory addressing

[Ani]

i would like to transfer the first 'n' bytes of one memory into another
memory, both of same width but different lengths. is there some way to
do this without using a loop?

I don't know whether a keyword or system task/function in SystemVerilog
predefined for that, maybe thru a struct manipulation with pointer
arithmetic a la C?

In Verilog there is no such keyword/system task. Since there no pointer
arithmetic in Verilog, there is no trick you can do without loop.

yeah thats what i thought...was just wondering if somebody could throw
up some cool trick!

An applicable "trick" you like depends upon your application.

You just want to get rid of a loop implementation, but don't forget
that even a keyword/predefined SystemVerilog/Verilog task might also
include a loop implementation.

Your requirement is that you want to "transfer" "n" bytes from a memory
to another. But you don't give much more information. Does the content
of "source memory" get updated? Then you cannot use a pointer
arithmetic. You must "copy" it.

Give us more info about your application and about the language you
want to use. Otherwise, the only thing I can recommend is a loop,
nothing else.
