Ocean Logic releases 1080p H.264 encoder and limited decoder with 8-16:1 compressed frame store that requires no off chip DRAM

Sydney, March 28 2011 -- Today Ocean Logic announces the 1080p H.264 Encoder and Limited Decoder IP Cores based on a new, patent pending, Compressed Frame Store (CFS) technology whose main features are :

• High compression (8-16:1) of the reference frame store, depending on the desired quality
• The bitstream is fully compatible with existing, third party decoders with no error/drift
• The technology is not restricted to the H.264 standard and it could be potentially applied to other video compression algorithms

This technology makes a highly compressed reference frame store practical that can result in the integration of the CFS memory in a SoC and the elimination of the external DRAM. This, in turn results in a very substantial reduction in the power requirements. CFS size can be smaller than 1 Mbit for 720p or ~2.2 Mbits for 1080p.

Ocean Logic believes that this unique technology will enable a new class of low power H.264 devices for consumer products such as camcorders, cameras, mobile phones as well as embedded applications in video surveillance and automotive.

The H.264 CFS Encoder is working in an Avnet FPGA board encoding 720p@30 video using a Xilinx Virtex-5 part as a technology readiness demonstration.The size of the H.264 CFS encoder is approximately 280 Kgates + 217 Kbits of single and dual port memories + CFS memory for a fast 130 nm process, at 250 MHz (1080p@30), worst case process, low voltage, worst case temperature (125 C).

Availability

The H.264 CFS Encoder IP core is immediately available as VHDL or Verilog source or FPGA netlist. The H.264 limited decoder will be available in Q2.

The design is fully synchronous, single clocked soft IP core. Only the rising edge of the clock is used and there are no transparent latches.

Customers wishing to evaluate the IP can request the bit accurate C model and the User's Guide. Selected customers can have access to a timed FPGA netlist.
