I have written a c++ prog. and now I want to turn it into a handheld

am having trouble finding out how the boards are made/programmed.
(it may sound silly, but I tore apart a small cheap cheap calculator
and as far as I can tell, It should function along the same lines
except that it may need more RAM to hold pre defined char. names)
This is a fairly serious undertaking.
I feel obliged to point out that in many ways it's much more difficult
to design something that's small, low-cost, low-power, etc., than
something big and impressive like a desktop computer.
As for how to design it: it depends heavily on the processing
capabilities you need, the volume you're planning to build, what
peripherals you need to support such as whether your display will do
bit-mapped graphics, or just numbers, and so on. Something that does
minimal calculation and only needs to run a numeric (segmented) display
can probably work quite nicely on an 8-bit microcontroller like an
8051. At the high end, some StrongARMs run at over 300 MHz.
In any case, none of this really has much to do with C++, so it's
undoubtedly off-topic here.
