Multiplication of a block of integers

[Frank Klemm]

This is a simple function multipliying a block of integers with 5000.

C code needs 6.35 clocks per item
unrolled C code needs 5.4 clocks per item
stupid assembler code needs 4 clocks
unrolled assembler code 2.26 clocks

Because of a factor of 1:2.4 between Assembler and C this may be interesting.

I know this is not a typical application, but it show some weak points.
