The 3D graphics processing unit (GPU) subsystem is based on
POWERVR® SGX544 subsystem from Imagination Technologies. It supports phone, PDA, and handheld gaming applications. The GPU can process different data types simultaneously, such as: pixel data, vertex data, video data, and general-purpose data.
The GPU subsystem has the following features:
- Multicore GPU architecture: two SGX544 cores. Shared system level cache of 128 KiB
- Tile-based deferred rendering architecture
- Second-generation universal scalable shader engines (USSE2), multithreaded engines incorporating pixel and vertex shader functionality
- Present and texture load accelerators
- Enables to move, rotate, twiddle, and scale texture surfaces.
- Supports RGB, ARGB, YUV422, and YUV420 surface formats.
- Supports bilinear upscale.
- Supports source colorkey.
- Industry-standard API supports DirectX® 9,
OpenVG™ 1.1, and
OpenCL™1.1 Embedded Profile
- Fine-grained task switching, load balancing, and power management
- Programmable high-quality image antialiasing
- Bilinear, trilinear, anisotropic texture filtering
- Advanced geometry DMA driven operation for minimum CPU interaction
- Fully virtualized memory addressing for OS operation in a unified memory architecture (MMU)
