IMX6 GPU/VPU
Description
Vivante’s fourth generation (Gen 4) Vega ScalarMorphic architecture provides a foundation for our newest series of low-power, high-performance, silicon-efficient GPGPU cores. Gen 4 products support the most advanced GPGPU APIs and profiles for leading applications that take full advantage of GPU Compute for vision processing, gesture processing, Advanced Driver Assistance Systems, Augmented Reality, and much more. These cores are available as GPGPU only cores targeting high performance Compute applications that do not require any 3D functionality (CC or Compute Cores) or as part of our standard 3D products that give full flexibility to application developers and product offerings.
