GPU - Graphics Processing Unit

The IMX6 contains 2D and 3D GPU support from Vivante with some variations based on the specific IMX SoC:

  • IMX6DUAL/QUAD:
    • Vivante GC2000 (3D GPU)
      • Clock: 600-800MHz (the IMX6 clocks this at 533MHz)
      • 176Mtri/s
      • 1000Mpxl/s
      • OpenGL ES 1.1/2.0/3.0
      • OpenCL 1.1 EP
      • Cores: 1
      • Shaders: 4 (Vec-4) and 16 (Vec-1)
    • Vivante GC355 (2D GPU - vector graphics)
      • 300Mpxl/s
      • OpenVG 1.1
    • Vivante GC320 (2D GPU - blit)
      • 600Mpxl/s
  • IMX6DUALLITE/SOLO:
    • Vivante GC880 GPU
      • Clock: 600-800MHz (the IMX6 clocks this at 400MHz)
      • 53Mtri/s
      • 266Mpxl/s
      • OpenGL ES 1.1/2.0/3.0
      • Cores: 1
      • Shaders: 1 (Vec-4) and 4 (Vec-1)
      • OpenVG 1.1 (no GC320 on this SoC, so 2D vector graphics is through the GC880)
    • Vivante GC320 (2D GPU - blit)
      • 600Mpxl/s

According to Freescale this GPU supports the following open standards:

  • OpenCL 1.1 Embedded Profile (EP) (Open Computing Language - framework for writing programs that execute across a heterogeneous platform consisting of CPUs, GPUs, DSPs, etc)
  • OpenGL ES 1.1/2.0 (Open Graphics Library - for 2D and 3D vector graphics)
  • OpenVG 1.1 (Vector Graphics Acceleration)

Software Support:

  • Yocto BSP packages:
    • gpu-viv-bin-mx6q
