Modyfing/replacing C funtion during STM32 work

I'd like to implement simple DSP job on my STM32F4 discovery board. I wish to have possibility to change it during STM32 work without flashing program memory. Can I do that?

It's like I compile some C funtion to my library, send it to target (via usb), who will update/substitute DSP processing function to the new one saving in into the SRAM. C language recognise function as an address of its beginning, right? I would implement like two SRAM spaces for two functions I will switch between them every time new one is completely copied into memory.

STM32 will constantly gather some input data (but NOT from USB-key), process it with my DSP function and sent it back to Codec that I will add to my target, don't worry about hardware now.
