TRDs are key components of the Xilinx Targeted Design Platform (TDP) strategy.TDPs from Xilinx provide customers with basic scalable design platforms
for the creation of FPGA-based solutions in a wide variety of applications and industries.

The Base Targeted AP SoC Reference Design
The Base TRD showcases various features and capabilities of the Zynq-7000 AP SoC Z-7020 device for the embedded domain in a single package using a Xilinx standard Zynq platform Linux-based video pipeline design. The Base TRD consists of two processing elements: the Zynq-7000 AP SoC processing system (PS) and a video accelerator based on PL. The AP SoC allows you to implement a specific functionality either as a software program running on the Zynq-7000 AP SoC PS or as a hardware design inside the PL. The Base TRD demonstrates an optimization of how you can seamlessly switch between a software or a hardware implementation, contributing to
ease of use. The TRD also demonstrates the value of offloading computation-intensive tasks onto PL, thereby freeing the CPU resources available for user-specific applications.
Software developers can leverage the Base TRD and start programming immediately using the widely known Eclipse-based integrated development environment (IDE), GNU compiler tool chain, Linux operating system (OS), and libraries. Embedded hardware designers now have immediate access to the industry standard ARM® Cortex™-A9 core processor system and video IPs running on PL out of the box. In addition, the TRD also provides customers with access to the various PL-based video components such as video direct memory access (VDMA), video timing controller (VTC), video test pattern generator (TPG), Sobel filter and the Xylon logiCVC-ML display controller

These IP cores are part of the video pipeline implemented in the PL.
The Base TRD consists of a PS based on the embedded ARM Cortex-A9 core processor, a video processing pipeline implemented in PL, and a Linux-based software application that includes a Qt-based graphical user interface (GUI) (doc.qt.nokia.com) to provide user control and monitoring. The Linux-based software platform and software application run on the ARM Cortex-A9 cores. The software application works in tandem with hardware and provides you with the choice of offloading computation-intensive processing to the PL-based hardware subsystem.
