Description
Xylon provides a complete set of logicBRICKS IP cores and related software drivers to enable use of the Qt, a leading cross-platform application and UI development framework, for rapid development of Linux software applications with a Graphical User Interface (GUI) on the AMD Zynq™ 7000 All Programmable SoC.
Minimum Zynq™ 7000 Adaptive SoC configuration to run the Qt requires the logiCVC-ML display controller IP core and the standard Linux framebuffer software driver. High-resolution graphics content require a very high usage of the SoC processing system and can cause an overall application’s performance bottleneck. XylonQPA plugin enables Qt 5.4 GUIs accelerated by the logiBITBLT 2D graphics accelerator IP core that improves graphics performance and offloads the processing system for other system tasks.
The bellow figure shows the benchmarked graphic performance of the common blending operation between two graphic objects (bitmaps) performed on the AMD ZC702 kit running the Linux OS and the QtPerf application for Qt graphic performance testings. The benchmark results shows that the logiBITBLT IP core and the XylonQPA plugin can deliver 2-3x performance improvement (for the specific graphics operation) and significant offloading of the processing system. The performance of real-life GUI applications depend on the overall SoC architecture, the software architecture and the number and type of used graphics operations.
