Fixed point 16/32 integer FFT library for the RaspberryPi and Android
This library is being created as I have a need to do very fast FFTs on low end devices not supporting the NEON instruction set.
The RaspberryPi is an ideal candidate for developing in gcc before porting to JNI for low spec Android devices, hence it's inclusion.
Fixed point 16/32 integer FFT library suitable for the RaspberryPi and Android devices.
Includes test stubs for gcc on the RaspberryPi and a Basic4Android wrapper from JNI.
It includes hand optimised ARMv6 assembler, demonstrating techniques such as pipeline stuffing to achieve maximum performance.

An arithmetic calculator for the most popular numerical systems.
...That's what makes this application. You can mix decimal, binary, octal and hexadecimal arithmetic operations using the symbols "+, -, *, /,^,". You can put "e" to use Napier's constant, put "pi" to use pi constant and put a "!" in the of numerical system form to factorization. So let's start doing the math in an instant with this application and save the rest of the time for more useful things of interest.
