Abstract
Advances in technology are making it possible to run three-dimensional (3D) graphics applications on embedded and handheld devices. In this article, we propose a hardware/software co-design environment for 3D graphics application development that includes the 3D graphics software, OpenGL ES application programming interface (API), device driver, and 3D graphics hardware simulators. We developed a 3D graphics system-on-a-chip (SoC) accelerator using transaction-level modeling (TLM). This gives software designers early access to the hardware even before it is ready. On the other hand, hardware designers also stand to gain from the more complex test benches made available in the software for verification. A unique aspect of our framework is that it allows hardware and software designers from geographically dispersed areas to cooperate and work on the same framework. Designs can be entered and executed from anywhere in the world without full access to the entire framework, which may include proprietary components. This results in controlled and secure transparency and reproducibility, granting leveled access to users of various roles.
Highlights
For hardware/software co-verification, a QTracer module is embedded in the QEMU interface that stores data of the 2D coordinate vertices and frame buffer into a file
3D graphics applications have gained significant popularity in recent decades
Designing in this way raises the level of abstraction of the primary specification, allowing designers to explore the architectural trade-offs and hardware/software partition decisions that need to be made at a higher level
Summary
For hardware/software co-verification, a QTracer module is embedded in the QEMU interface that stores data of the 2D coordinate vertices and frame buffer into a file. Communication interface and 3D graphics SOC This section introduces the hardware development environment of the proposed co-design framework consisting of two hardware parts. A slave read process requires the SC receiver to return data from the QEMU, and has successfully locked the AHB bus, resulting in a deadlock.
