Abstract: Perceptual Lossless Compression (PLC) is a novel compression standard directed by the Audio Video coding Standard (AVS) work group. It defines a lightweight, low-latency, and visually lossless image compression framework, which offers an alternative mezzanine codec for most user-agnostic on-chip compression scenarios, alleviating the tension between growing transmission demands and expensive integration upgrades. In this paper, the technical designs in the development process of PLC will be fully introduced. The balance between feature modeling and ASIC implementation costs will be present throughout. A high throughput and low hardware complexity implementation will be detailed and evaluated namely HIM. Hopefully, the design of the PLC standard and HIM framework will bring new inspiration for the emerging low-latency interaction systems.
