GW5

The GW5 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 GW5 includes an innovative High Dynamic Range (HDR) Image Signal processor (ISP), indie’s proprietary 5th-generation eWARP® geometric processor, 2D graphics functionality, and a computer vision processor. Designed in a 28nm process to enable small, low-power automotive cameras on the edge, the GW5 supports ASIL-B and AEC Q100 Grade 2.

The GW5 supports up to 8MP for conventional sensors and up to 5MP 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 a 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 GW5 reduces system component count by requiring no external double data rate (DDR) memory and incorporating dual camera inputs. GW5 based designs can be rapidly brought to market by leveraging indie’s software design and evaluation kits.
