High Performance platform for High Definition encoding
The hybrid solution consists of high-level encoding software from MainConcept, which runs on a Windows or Linux PC platform, and low-level encoding software from Aspex, which runs on the Linedancer processors on Aspex’s Accelera 3000 PCI/PCI-X plug-in card and Accelera 3500 PCI-express card
The accelerated solution maintains the same API as MainConcept’s leading MPEG-2 and H.264 software encoder, allowing existing applications to immediately benefit from a significant uplift in encoding performance.
With more than 16,000 processing elements operating in parallel, the Accelera platform provides acceleration for key processor-intensive encoding tasks, such as motion estimation, DCT/iDCT transforms, quantization and run-length encoding.
Linedancer’s unique scalability means that multiple boards can be added to a system to achieve faster-than-realtime HD encoding performance for demanding applications.

Advanced, hierarchical motion estimation
Motion Estimation is a highly parallel task, with each macroblock of pixels being compared with hundreds or thousands of other macroblocks to determine the “best fit”.
Aspex ’s parallel implementation of Motion Estimation uses a variety of techniques to achieve significantly higher performance than PC software implementations.
- ± 256 pixel X & Y motion search range
- ± ½ pixel motion search resolution
