Overview

The Graphic 2D Accelerator (G2D) is a specialized DMA dedicated to image manipulation. It can perform the following operations:

  • Filling a part or the whole of a destination image with a specific color.
  • Copying a part or the whole of a source image into a part or the whole of a destination image.
  • Copying a part or the whole of a source image into a part or the whole of a destination image with a pixel format conversion.
  • Blending a part and/or two complete source images with different pixel format and copy the result into a part or the whole of a destination image with a different color format.

All the classical color coding schemes are supported from 4-bit up to 32-bit per pixel with indexed or direct color mode.

The G2D has its own dedicated memories for CLUTs (color look-up tables).

Key features

  • One internal slave bus for register config
  • One internal master bus for memory access(the addr width of the bus can be 32bit~64bit, the data width of the bus is 32bit)
  • Copy from an area to another
  • Copy with pixel format conversion between source and destination images
  • Copy from two source with independent color format nad blending
  • Area filling with a fixed color
  • User programmable working area size
  • User programmable offset for sources and destination areas
  • User programmable sources and destination addresses on the whole space
  • Up to 2 sources with blending operation
  • Alpha value can be modified (source value, fixed value or modulated value)
  • User programmable source and destination color format
  • Up to 11 color formats supported from 4-bit up to 32-bit per pixel with indirect (L8,AL44,AL88,L4) or direct (ARGB8888,RGB888,RGB565,ARGB1555,ARGB4444,A8,A4) color coding
  • 2 internal memories for CLUT storage in indirect color mode
  • Automatic CLUT loading or CLUT programming via the CPU
  • User programmable CLUT size (The max size is 32x256bit)
  • 4 operating modes: register-to-memory, memory-to-memory, memory-to-memory with pixel format conversion, and memory-to-memory with pixel format conversion and blending
  • Abort and suspend of G2D operations
  • Watermark interrupt on a user programmable destination line
  • Interrupt generation on bus error or access conflict
  • Interrupt generation on process completion
  • User programmable images size
  • Supports 3 mirroing modes (X,Y,XY)
  • Supports cut window
  • Supports down sample(sample rate can be 1~8)
  • Supports RGB pixel order and BGR pixel order

Tape-out Risk in the Age of Edge AI: The Case for GPU IP

A full SoC tape-out at 5nm approaches $400M in fully loaded, non-recurring engineering and mask costs. At 3nm, estimates push past $600M. Every IP block on that die is a commitment to a set of assumptions about what the silicon will need to do. In AI, those assumptions have a shorter shelf life than they used to.

What Does a GPU Have to Do With Automotive Security?

The automotive industry is undergoing the most significant transformation since the advent of electronics in cars. Vehicles are becoming software-defined, connected, AI-driven, and continuously updated. This evolution brings extraordinary new capability – but it also brings greater levels of cybersecurity and functional-safety risks.

How Alternate Geometry Processing Enables Better Multi-Core GPU Scaling

Scaling GPU performance across multiple cores sounds simple in theory: add more cores, get more performance. In practice, it’s one of the toughest challenges in graphics architecture. While some workloads scale well thanks to their independent nature, some workloads, especially geometry processing, introduce order dependencies that make linear performance scaling a tricky problem to solve for every GPU architecture in the industry.
