summary

MSVP is a server-grade video accelerator that processes up to 1 billion pixels per second while consuming less than 10 W, implemented as a 100 mm² 7 nm SoC with the encoder occupying >50% of die area. It decodes H.264/H.265/VP9/AV1, encodes H.264 and VP9, uses 25-tap 2D scalar filters, a three-stage motion search with ±512 horizontal, ±160 vertical search and parallelized RDO/rate estimation, and runs quality metrics (SSIM, MS-SSIM, VIF, PSNR, blur) ~25× per upload; results yield 9× faster with half the energy versus software.
