Not familiar with the device, but based on my knowledge of Java for PCs: 
if you need performance, try doing it in Java first anyway and then 
compare the two. Modern JIT-compiled Java may well be *faster* than 
calling out to C code - I suspect that this is down to JNI overhead.

If the device doesn't have a JIT, then the above is probably wrong, in 
which case my apologies.
