JPEG 2000 decoder for high-speed applications (up to multi-channel DCI 2K and 4K, HD 1080i and 1080p)
The BA109 IP core is a JPEG 2000 hardware decoder dedicated to DCI (Digital Cinema Initiatives) and HD video applications. It decodes streams compliant with the ISO/IEC 15444-1 specification (JPEG 2000). It is compliant with the DCI recommendation for video coding. It applies JPEG 2000 decoding on un-tiled large color frames with 4:4:4, 4:2:2 or 4:2:0 sub-sampling.
The core performs the complete video decompression operations of the normalized decoding process: stream parsing and header decoding, entropy decoding, inverse quantization, inverse discrete wavelet transform (IDWT) and inverse color transform (ICT/RCT). It supports a JPEG 2000 j2c file at its input interface and generates decoded samples at its output interface under the following formats: 4:4:4, 4:2:2 or 4:2:0 color mode with 12-bit samples.
The core is optimized for speed and is able to deal with the demanding DCI and HD processing speeds: it is able to provide a single-chip FPGA solution for all 2K @24 fps, 2K @48fps, 4K @24fps, 720p30/60, 1080i and 1080p30/60 distributions. The flexible FPGA architecture allows the user to build a secure decoder by integrating Silex Insight cryptography decoders (DCI AES).
