Description
ATEME H.264 bitstream intellectual property (IP) core is a VHDL hardware module able to encode the macroblocks information using CABAC coding mode, and to generate H.264 bitstream compliant with ISO/IEC14496-10 specification. NAL and RBSP headers (a subsection of the NAL unit) are not generated, but included as raw data in the bitstream. The neighborhood information necessary for encoding is autonomously managed.
The module is designed to compute full-size video sequences. It can be adapted to any format.
The IP uses a generic bus interface for registers and streams. It is delivered encapsulated with two AHB agents:
- AHB slave for registers access
- AHB master to access directly data in external memory
The three associated modules (register access, address generation and management of data accesses, and master AHB interface) are delivered in source code with the H.264 module. Thus the IP can be used either directly, for example by a CPU, or with all associated modules in a system-on-a-chip (SoC) design.
For information on footprint and size, logic elements (LEs), and memory usage, please contact ATEME.
Deliverables
Deliverables include:
- CABAC/CAVLC bitstream IP in VHDL source code
- User's manual
- Simulation files
- Reference software on PC (Windows)
The reference software encodes a video file, and delivers output files, exactly the way the IP does. This allows to feed known data into the IP and to compare the IP output with the software output for validation.
An evaluation version of the IP is available. As an option, a PCI board with an Altera® Stratix® II FPGA is also available.
