ChipWrights, Inc.—part of AD Group—Announces a new color pipeline solution for cameras using non-System-on-Chip (SoC) sensors based on ChipWrights’ CW5631 SoC. The solution requires a CW5631 SoC and a DDR2 DRAM; it can be employed in tandem with a second CW5631 SoC, which can be used as a system processor or as a stand-alone image sensor pipeline in existing camera designs.
The chip has 16-bit streaming input and output ports, which can be configured for BT.601 or BT.656 operation. The image pipeline is implemented in software that runs on ChipWrights’ proprietary DSP and can be as complex or simple as required. The pipeline inputs raw sensor data in Bayer format and outputs the image as YUV422i.
“The industry has been waiting for such a flexible, general purpose solution for the image pipeline in custom cameras,” said ChipWrights’ President Cary Robins. “System designers are eager to leverage an image pipeline that solves the problem efficiently and at low cost but also allows them to enhance with their own system knowledge and algorithms to provide even higher quality results. I am excited to see what our customers do with this technology, “ he added.
ChipWrights will release the Color Pipeline’s Source Code to qualified customers. Customers can modify and enhance the code for their applications. The baseline release includes:
A Library of Image Enhancement Features is available for free as binaries. The source can be purchased. Initial features include:
Additional features may include:
The CW5631 SoC offers the flexibility and computational power to implement a wide variety of options. The CW5631 SoC includes programmable timing generators for Horizontal and Vertical Sync timing and an I2C Master to configure and control the image sensor. In a typical application the device consumes about 350 mW.
ChipWrights will offer two hardware reference designs.
