CODAJ12

JPEG Codec Series
CODAJ12 is a standalone and high-performance JPEG Codec IP that performs the JPEG baseline/extended sequential and M-JPEG decoding and encoding. Fully compliant with the baseline and extended sequential DCT mode of ISO/IEC 10918-1 JPEG standard, CODAJ12 is capable of supporting MJPEG streams with various color formats supporting resolutions up to 32Kx32K. Its fully hardware-based architecture allows for very high performance and low power consumption and makes it suitable for a variety of digital imaging applications. On-the-fly pre-and post-image processing can also contribute to the improvement of memory bandwidth efficiencies.
