VISENGI's H.264 Encoder is an advanced video compression solution renowned for its high-performance capabilities. Designed to accommodate modern high-resolution demands, this encoder allows UltraHD 4K 60 encoding on lower-end FPGAs like Spartan/Cyclone and extends to 8K 30fps on mid-range models such as Arria 10 and Zynq. Distinctive for its single-engine design, it provides the lowest latency and highest throughput in the industry, processing over 5.2 pixels per cycle. It supports various profiles such as the High 4:4:4 Predictive Profile, ensuring that full-color fidelity is maintained through options like 4:4:4, 4:2:2, and 4:2:0 inputs.
The encoder is engineered to handle multiple inputs simultaneously, up to 32, enhancing its utility in complex systems with a single instance deployment. Its versatility in resolution scaling means it can manage any resolution from QVGA to 8K seamlessly. Real-time variable bit rate (VBR) and constant bit rate (CBR) control offer optimal management of H.264 parameters to meet specific video quality and file size requirements.
Interface-wise, the encoder utilizes an AXI-Lite configuration and supports AXI3/4 for data I/O, making it broadly compatible and easy to deploy. Its robust architecture includes embedded DMA engines, optimized pixel input modes, and motion estimation options that contribute to its efficiency and performance. The output aligns with industry standards, encapsulating data in raw .264 byte streams and providing options for reconstructed video outputs.
