Ocean Logic has recently introduced a baseline H.264/AVC 1080p HDTV encoder. Some of the characteristic of OL_H264: ¨ Fully compatible with the ITU-T H.264 baseline specification. ¨ Proven in FPGA : VGA (640x480) at 30 fps in VirtexII4000-4 ¨ Profile level 4.1, can be decoded by Main Profile decoder. ¨ Supports up to the highest HDTV video resolution (1920x1080 @ 30 fps progressive). ¨ Very low operational frequency : from ~1.5 MHz for QCIF @ 15 fps to ~250 MHz for 1920x1080 @ 30 fps. ¨ Single core HDTV support in FPGA : 720p (1280x720) at 30 fps in high end FPGAs (Virtex4) . ¨ 4 CIF (704x576) at 30 fps in low end FPGAs (Spartan3-4, slowest speed grade). ¨ No CPU required for encoding. ¨ Variable Bit Rate (VBR) and Constant Bit Rate (CBR). ¨ Very low latency in VBR (~1.1 ms for VGA @ 30 fps). ¨ Motion vector up to –16.00/+15.75 pixels (search area is 32x32 pixel wide down to quarter pixel). ¨ Support for most of intra4x4 and all intra16x16 modes. ¨ Multiple slices support for better error resilience. ¨ Block skipping logic for lower bitrate. ¨ Deblocking filter for better quality. ¨ External memory interface tolerant of high latencies and delays, ideal in a SoC system or in a shared bus with a CPU. The memory interface can be clocked at a different frequency from the core for easier integration. ¨ Supports YUV 4:2:0 video input ¨ Min Clock speed = 4 x the raw pixel clock speed ¨ Low gate count (from 129K gates + 100 Kbits of RAM for real time VGA encoding to 178 Kgates + 100 Kbits of RAM for real time 1080p encoding). ¨ Simple, fully synchronous design. ¨ Available as fully functional and synthesizable VHDL or Verilog soft-core. Available now. C model of the IP is available now for evaluation. Download the datasheet. |
