That sounds like Intel Quick Assist (QAT). That's a not-greatly-documented technology that's included in some processors (including a bunch of Celerons, but mostly Xeons) and in PCIe cards. They are used in firewalls, ssl terminators and storage systems, as they can provide Gbps of compression or cryptography. See one of the older cards: https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/quickassist-adapter-8920-brief.pdf https://www.intel.com/content/dam/www/public/us/en/documents... Netgate sells one 8950 based card for it's firewalls: https://shop.netgate.com/products/netgate-cpic-8955-cryptographic-accelerator-card-with-qat https://shop.netgate.com/products/netgate-cpic-8955-cryptogr... STH had a report this summer: https://www.servethehome.com/intel-quickassist-parts-and-cards-by-qat-generation/ https://www.servethehome.com/intel-quickassist-parts-and-car... This cards are expensive when bought new, but you can probably buy some of them cheaply in eBay. Please don't drive the prices up ;)
