Hi all,

I have been searching about the floating point support on G1 phone
(aka the HTC Dream phone) for a few hours.

So far, my conclusion is that the ARM-based Qualcomm MSM7201 CPU does
not have VFP (floating point coprocessor) and therefore floating point
calculations have to be done via software-float.

This is quite disappointing as I am interested in developing
applications with heavy math.

However, I also notice that the Qualcomm  CPU has QDSP4000™ and
QDSP5000™ high-performance digital signal processors (DSP), according
to http://www.qctconnect.com/products/msm_7201.html

Therefore, here is my question: would it be possible to leverage the
DSP modules in the MSM7201 CPU to do the floating point math?

Also, I would like to develop the heavy-math modules in C/C++ and call
it via JNI, and so I just want to double-check whether this is a
feasible approach.

Thanks!
