Intel® Stratix® 10 SX SoC devices have a feature set that is identical to the Intel® Stratix® 10 FPGA devices, with the addition of an embedded quad-core 64-bit Arm* Cortex* A53 Hard Processor System.

Common to all Stratix 10 family variants is a high-performance fabric based on the new HyperFlex core architecture that includes additional Hyper-Registers throughout the interconnect routing and at the inputs of all functional blocks. The core fabric also contains an enhanced logic array utilizing Intel’s adaptive logic module (ALM) and a rich set of high performance building blocks including:

To clock these building blocks, Stratix 10 devices use programmable clock tree synthesis, which uses dedicated clock tree routing to synthesize only those branches of the clock trees required for the application. All devices support in-system, fine-grained partial reconfiguration of the logic array, allowing logic to be added and subtracted from the system while it is operating.

All family variants also contain high speed serial transceivers, containing both the physical medium attachment (PMA) and the physical coding sublayer (PCS), which can be used to implement a variety of industry standard and proprietary protocols. In addition to the hard PCS, Stratix 10 devices contain multiple instantiations of PCI Express hard IP that supports Gen1/Gen2/Gen3 rates in x1/x2/x4/x8/x16 lane configurations, and hard 10GBASE-KR/40GBASE-KR4 FEC for every transceiver. The hard PCS, FEC, and PCI Express IP free up valuable core logic resources, save power, and increase your productivity.
