This PCI Express* (PCIe*)-based FPGA accelerator card for data centers offers both inline and lookaside acceleration. It provides the performance and versatility of FPGA acceleration and is one of several platforms supported by the Acceleration Stack for Intel® Xeon® CPU with FPGAs. This acceleration stack provides a common developer interface for both application and accelerator function developers, and includes drivers, application programming interfaces (APIs), and an FPGA interface manager. Together with acceleration libraries and development tools, the acceleration stack saves developers time and enables code re-use across multiple Intel FPGA platforms. The card can be deployed in a variety of servers with its 1/2 length, single-slot form factor, low-power dissipation, and passive heat sink. The versatile Intel Programmable Acceleration Card with Intel Arria® 10 GX FPGA (Intel PAC with Intel Arria 10 GX FPGA) can be implemented in many market segments, such as big data analytics, artificial intelligence, genomics, video transcoding, cybersecurity, and financial trading.
