This middleware provides a standalone driver for the graphics subsystem Traveo II Cluster devices. It is a precompiled binary along with headers that provide the driver API. The following devices are supported by this driver:
- CYT4DNJBZS
The graphics subsystem integrates internal video RAM, a 2D graphics core, and interfaces for video input and output processing. Target use case is to drive low- and mid-end automotive cluster and head-up displays up to HD 720p resolution. Alternatively, the subsystem can operate in video feed-through mode for high-end applications up to Wide HD (2880x1080). This makes TVII-C-2D devices a safety companion to a non-Automotive graphics SoC and can overlay or autonomously display safety relevant elements.
The key function is an option to render graphics directly to display (on-the-fly) instead of to a frame buffer in RAM. This enables the internal video RAM to become sufficient for 720p graphics and allows customers to save BOM cost, because the system does not require external DDR RAM. While this technique is common for simple sprite graphics, it is unique in context of 2D GPUs with sophisticated operations such as image rotation and perspective correction (2.5D).
