D/AVE NX – 3D graphics IP core for FPGAs and ASICs
D/AVE NX is the latest and most powerful addition to the D/AVE family of rendering cores. It is the first IP to bring full OpenGL ES 2.0/3.1 and VULKAN rendering to the FPGA and SoC world and is prepared to support OpenGL SC (Safety Critical). Targeting graphics user interfaces on displays up to 4K x 4K resolution in the Industrial, Medical, Military, Avionics, Automotive and Consumer markets D/AVE NX is designed to meet the sweet spot of performance, footprint and functional safety.
By enabling the use of state of the art shader based APIs even on small devices high quality 2D and full 3D applications can be satisfied using the D/AVE NX core. The possibility to work with a modern graphics programming language like OpenGL ES 2.0 enables the user to rapidly build high-end user interfaces (e.g. based on QT, Android or WebGL) and makes new, future proof implementations possible.
The D/AVE NX IP core can scale easily to fit exactly into the resource/performance sweet spot for a particular application. Thus entire device families can be equipped with differently scaled variants of the core, making all of them fully software compatible. A single unified software stack and the guarantee to produce exactly the same visual result (at different speeds) allows saving significant development resources.
D/AVE NX is highly efficient as the internal multi-level scheduler can maximize the utilization of every HW element even better than the fixed function pipeline of the successful D/AVE cores could. Scheduling also does not have to be pre-computed in the compiler simplifying the compiler and driver architecture considerably.
D/AVE NX Graphics Turnkey System Solution for Intel PSG SoCs
D/AVE NX is provided within evaluation kits for Intel PSG Arria10 and Stratix10 SoCs including a complete solution based on Yocto-Linux and Qt- as well as OpenGL ES 2.0 example applications. The evaluation kits include the D/AVE NX QSys component, drivers and documentation, i.e. everything that is needed for integration, evaluation and prototyping purposes.
Overview of the components included in the D/AVE NX Turnkey System Solution Evaluation Kit

TES provides Khronos conform OpenGL ES 2.0/3.1 and EGL drivers. The drivers rely on a low level D/AVE NX driver layer abstracting hardware details like the register access and making porting to different CPUs / Operating systems a lot easier.
All drivers have the following features:
- Fully reentrant & thread-safe
- Minimal OS dependency (HAL part separated)
- No inline assembler required
- Support for multiple D/AVE NX instances
- Multi-threading support, i.e. multiple applications can use D/AVE NX concurrently
- Small memory footprint
