The UHT-JPEG2K-E core from Alma Technologies is a very high performance self-contained JPEG 2000 encoder IP core, designed to provide the extreme performance needed by modern image and video compression applications that have to cope with massive resolutions and pixel rates. The core implements Part 1 of ISO/IEC 15444-1 image compression standard and supports lossy and lossless encoding of 4:4:4, 4:2:2, 4:2:0 and 4:0:0 video streams, in 8 up to 16 bits sample depths.
Using multiple internal compression engines, the UHT-JPEG2K-E offers the needed performance through its scalable parallel architecture. Each input image or video frame is split internally into pieces and each piece is allocated to one of the multiple internal compression engines. The encoded output streams of the compression engines are combined in a single output stream. These operations are done in a way that is transparent to the system utilizing the IP, abstracting all the parallelization complexity from the rest SoC components. The number of internal compression engines is configurable before synthesis, adapting to the implementation technology speed, and non-critical resources are shared between the multiple compression engines.
