The GW54x0 is an advanced Camera Video Processor (CVP) System-on-Chip (SoC) designed for advanced driver assistance systems (ADAS) and RGB infrared (RGB-IR) in-cabin sensing. The GW54x0 includes an innovative High Dynamic Range (HDR) Image Signal processor (ISP), indie’s proprietary 5th-generation eWARP® geometric processor, 2D graphics functionality, and a DSP processor. Designed in a 28nm process to enable small, low-power automotive cameras on the edge, the GW54x0 supports ASIL-B and AEC Q100 Grade 2.

The GW54x0 supports up to 8MP for conventional sensors and up to 2MP for RGB-IR sensors.

RGB-IR processing uses a proprietary de-mosaic algorithm that processes 4×4 RGB-IR filter array patterns. The RGB output mode is optimized for correct color and full IR removal. The IR-only output mode features resolution recovery achieving comparable performance to monochrome IR sensors with 4X the pixel count. Video output(s) are configurable between a dual RGB + IR output or an signal to noise ratio (SNR) optimized day/night mode switching output.

The HDR ISP supports the most advanced HDR, and LED Flicker Mitigation (LFM) techniques available on the
latest automotive sensors. The Vector Graphics Engine renders high resolution real-time graphics to overlay on
the video stream enabling compelling user interfaces.

The GW54x0 reduces system component count by requiring no external double data rate (DDR) memory and
incorporating dual camera inputs. GW54x0 based designs can be rapidly brought to market by leveraging indie’s
software design and evaluation kits.
