AMAP4PDISP, Apollo4 Plus Display Kit
The Apollo4 Plus is the latest addition to Ambiq’s portfolio of power efficient processers engineered for battery-powered endpoint devices.
An integrated GPU and display controller supports vector graphics,anti-aliasing, four layers of alpha blending, and dithering. Operating at
up to 192 MHz and with 4.75 MB of combined memory, developers can differentiate their products with bigger and richer display user interfaces
without sacrificing battery life. The Apollo4 Plus display kit includes an Apollo4 Plus EVB baseboard and Apollo4 Plus display shield that includes an AMOLED 454x454 display
with a MIPI DSI interface. Use I2C for touch capability on the display. The kit also contains a Hex-MSPI interface for fast access to external PSRAM.
Feature Highlights:
- Fully programmable engine with a very long instructions word (VLIW) instruction set
- Command list based direct memory accesses (DMAs) to minimize CPU overhead
- 4:1, 4:1 with alpha and 6:1 Compression
- 2D drawing:
Pixel/line drawing
Filled rectangles
- Triangles (Gouraud shaded)
- Blit support for rotation, mirroring, stretch, source and/or destination color keying, and format conversions
- Color formats: 32/16/8-bit with/out alpha, Grayscale, RGB
- Full alpha blending with programmable blending modes
