‘Pulsar-AV1’ is a fully hardwired AV1 video encoder IP that offers high computational and compression efficiency beyond customer-grade.
As the amount of video data in internet traffic grows, storage and network costs for streaming services are increasing. Optimizing video encoding is critical for cost-effective streaming services. Video encoding is a technique for reducing the size or bitrate of a video without negatively impacting its human-perceived quality.
Optimizing encoding involves moving to newer, more compression-efficient codecs. Since AV1, the next-generation codec standard with high compression efficiency, emerged as an alternative to the legacy H.264, AV1 adoption has been growing every year. However, software-based AV1 encoders have high computational overhead, making it difficult to achieve a meaningful break-even point and cost savings for the services gained by replacing existing codecs.
The vendor has leveraged semiconductor design techniques such as High-Level Synthesis to implement AV1 hardware IP, offering high computational and compression efficiency beyond customer-grade.
