CycloneIV Reconfiguration from network without rewriting flash

Hi Simon,

Are you in the process of designing a custom board? If so, then all you need is an intelligent configuration controller, eg., a microcontroller with external memory for configuration data storage. That storage can be non-volatile (SD card), or volatile (SDRAM) depending on the capabilities of your microcontroller. The FPGA can then be configured by the microcontroller using passive serial or fast passive parallel.

I doubt Cyclone IV will support OpenCL, so you'll want to leave that "thought" for another project.

Cheers,

Dave
