Ocean Logic is a provider of compression and encryption IP cores.
Our encryption line includes AES, DES, Triple DES, MD5, SHA-1 and SHA-256.
Our compression line includes QOI Lossless Image Compression Encoder and Decoder, H.264 Baseline Encoder and limited Decoder and, in the past, MPEG-4 Encoder and JPEG Encoder/Decoder.
Datasheets are available on the Downloads page.
The JPEG Encoder/Decoder was acquired by InSilicon and it is now part of Synopsys DesignWare.
All the encryption and H.264 IP cores above are proven in both ASIC and FPGA.
In 2022 we introduced a QOI Lossless Image Compression Encoder and Decoder IP core. These are a low footprint, high performance implementations of the QOI algorithm. Both Encoder and Decoder are capable of processing up to ~800 Mpixels/s in high end FPGAs and more than 4K@30 in low end ones. White paper here.
In 2011 we introduced a new H.264 Baseline Encoder based on Compressed Frame Store (CFS) technology (patents granted in US, China, Japan and Korea) that :
- is compatible with existing H.264 decoders
- allows to compress the reference frames 8-16:1 with no error/drift in the reconstruction when a third party decoder is used
Such high level of compression allows the CFS memory to be integrated on the same chip as the encoder. This eliminates the need for power hungry DRAM. Also, because of the high compression, the CFS memory is rarely accessed. This results in extreme low power.
An overview of the benefits and applications of the technology is available here and also here. A Virtual Reality Camera white paper using the CFS technology is available here.
This technology is currently available for licensing as the exclusive license to a large corporation has now expired. This has resulted in a SoC capable of H.264 encoding of 1080p@30 video with I and P frames and without external DRAM. This SoC is available now.
