This video encoder supports the Constrained Baseline Profile of the H.264 standard It implements an ultra-high throughput, UHD- capable hardware encoder that is optimized for ultra-low-latency video streaming at low bit rates. The H264-E-BPF requires significantly less silicon area than most equally capable H.264 cores allowing for cost-effective FPGA implementations. Its small silicon footprint, low memory bandwidth, and zero software overhead enable H.264 coding at an extremely low energy cost. Depending on its configuration the core is able to process Full-HD or UHD/4K video on Altera FPGAs. The core produces high quality video, even at low bit-rates, and features extremely low latency. It uses a constant Qp to output VBR streams, or automatically regulates Qp to output CBR streams. In CBR mode it responds rapidly to video content changes. This can be combined with Intra-Refresh coding to effectively eliminate bit-rate peaks, while preserving the periodic intra-coded references.
The core can be mapped to any Altera Family (provided sufficient silicon resources are available) and optimized to suit the particular project's requirements. When configured to process 1 pixel every 2 clock cycles (H264-E-BPf/2) the core synthesizes to 20k ALMs, 816k Memory bits, and 18 DSP blocks. Under this configuration, It can process 720p60, 1080p50 on several Altera FPGA devices. When configured to process 1 pixel every clock cycle (H264-E-BPf/1) the core synthesizes to 38k ALMs, 1.1M Memory bits, and 36 DSP blocks. Under this configuration, It can process 1080p60, or UHD/4k at 25 or 30fps on several Altera FPGA devices.
