Image Processing Project on the DE2 board

Alright! Let me see if I get this correctly:)

I attached a block diagram I made to represent the system I want to implement.

The solid lines represent the control signals used for interfacing the devices and the dashed lines are the data paths. The red line would be the data path of the configuration bits (HDL algorithms such as the JPEG compression) used to configure the FPGA portion for the data processing block. The black one are the buses for the image data being manipulated.

For the red line, the scan chain I imagined is like that, that the configuration bit stream would be scanned and loaded by the controller into the FPGA. Can I do this as direct from the SD Card into the FPGA processing block with the controller just commanding the devices? OR am I missing something in this part? (I didn't include the RAM I can use to store the configuration bits anymore)

For the controller block, I divided it into two parts, the interface to the other devices and the scan-chain part. Is this logical?

Furthermore, You mentioned that I have to implement a controller for the reconfiguration when I unplugged the Quartus and the JTAG. Is the controller in the diagram one in the same?
