-The DPTI demo consists of a Vivado hardware project, an SDK project for the MicroBlaze processor, and a Windows application written in Visual Studio. Using the aforementioned, the user can communicate with the Nexys Video's on-board DDR memory. Using a small Windows application, a file can be selected and sent to the Nexys Video via the USB PROG port at a specified memory address. After the transfer has been completed, it can then be read back and saved on the PC's hard drive at a specified location.+The DPTI demo consists of a Vivado hardware project, an SDK project for the MicroBlaze processor, and a Windows application written in Visual Studio.
