# Dave2D GPU (/integration/chip_vendors/alif/dave2d_gpu)



Alif Ensemble chips contain a [D/AVE 2D](https://www.renesas.com/document/mas/tes-dave2d-driver-documentation)
GPU. LVGL renders on it through the same **Dave2D** [draw unit](/main-modules/draw) that is used on
Renesas devices, because both platforms expose the same D/AVE 2D driver API. No Alif-specific draw
unit is required.

Usage [#usage]

Set <ApiLink name="LV_USE_DRAW_DAVE2D" /> to `1` in your `lv_conf.h`:

```c title=" " lineNumbers=1
#define LV_USE_DRAW_DAVE2D 1
```

The [alif\_m55-lvgl](https://github.com/alifsemi/alif_m55-lvgl) project used in the
[Overview](/integration/chip_vendors/alif/overview) guide already has the draw unit enabled, so it
accelerates rendering out of the box.

Accelerated Operations [#accelerated-operations]

The draw unit offloads most of LVGL's drawing operations to the GPU while the CPU stays free for
the rest of the application:

* Rectangle drawing, even with gradients
* Image drawing, scaling, and rotation
* Letter drawing
* Triangle drawing
* Line drawing

Anything the GPU cannot handle is rendered by LVGL's software renderer.

The draw unit itself, its supported image color formats, and its tuning options are described on
the [Renesas Dave2D GPU](/integration/chip_vendors/renesas/dave2d_gpu) page.
