// Without a (void*) cast, the ARM compiler makes the assumption that the float* pointer is naturally aligned
// according to it's type size (aligned along 4 byte boundaries) and thus tries to call a more optimized
// version of memcpy() which makes this alignment assumption also. When reading back from a file of course our pointers
// may not be aligned, hence we need to avoid the compiler making this assumption. The (void*) cast serves this purpose,
// and causes the ARM compiler to choose the slower, more generalized (unaligned) version of memcpy()

// For more about this compiler behavior, see:
