Nios system without jtag communication

[Altera_Forum]

Is it possible to use a nios based system even if the jtag communication cable is detached?? 

If I want to make an application in which some data is to be processed without having a host computer? so is it possible? How? Should i use flash programmer??

I think it is possible, but you need to buy a NiosII license.

You can now get a Low end Nios for free. See:

The jtag communication port is generally used as a debug port. It allows communication to NIOS via the same port where you personalize the FPGA and download your firmware. This configuration, however, is volatile, and is lost during a power cycle. For a stand alone application, you will need to provide a flash device that the FPGA will read upon power-up. The flash would also contain your firmware. No PC communication would be required. Altera has utilities that allow you to program the flash via a Byte or USB blaster, so it is a bit confusing when first starting out.

By flash device you mean flash memory of a development board? i am using DE2 cyclone II board which has flash memory...used for active serial programming as well...?
