Description
ATEME's H.264 in-loop deblocking filter intellectual property (IP) core is a hardware module able to filter the macroblocks information meeting ISO/IEC14496-10 specification. The IP has two input data paths: one receives control words, and the other receives current macroblock pixels to process. The neighborhood information necessary for filtering 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.
The IP has been optimized. For information on footprint and size, logic elements (LEs), and memory usage, please contact ATEME.
Deliverables include:
- Loop deblocking filter IP 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 like the IP. This allows you to feeding 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.
