All TPG processing parameters other than image size can be changed dynamically and the change is picked up immediately. If the image size needs to be changed on the fly or the entire system needs to be restarted, it is recommended that pipelined Xilinx ® IP video cores are disabled/reset from system output towards the system input, and programmed/enabled from system output to system input.
Note: A reset to the IP is required when the TPG is switched from passthrough mode to generate mode or from generate mode to passthrough mode.
