OL_MPEG4 is a real
time video MPEG-4 encoder capable of processing 4CIF resolution at 30 fps :
- Fully compliant with the ISO/IEC 14496-2.
- Multi-channel version proven in silicon.
FPGA demo for single channel version available.
- Real time encoding of video beyond 4CIF
(704x576) at 30 fps.
- Advanced Simple Profile Level1 to 5
- Motion
vector up to +15.5/ -16.0 pixels (I-VOP and P-VOP video
objects).
- DC
Prediction.
- The
core includes IEEE1180 compliant DCT and type 1 quantizer.
- Very
low gate count (approx 39 K gates + 25 Kbits of RAM in 0.18 u for 4CIF
@ 30 fps).
- Very
low clock speed (from ~3 MHz for QCIF @ 15 fps to ~98 MHz for 4CIF @
30 fps).
- Fully
synchronous design.
- Available
as fully functional and synthesisable VHDL or Verilog soft-core.
- Test
benches provided.
Available now.
C model of the IP is available now for
evaluation.
A special version of this core, capable of
simultaneous multi-channel encoding, has been delivered to a video surveillance
customer and functional silicon has been received.
