The main advantage of the Intel® Agilex™ board is the 400-Gigabit Ethernet capability, specially designed for SmartNIC applications.
The FPGA is an Intel® Agilex™ I-Series SoC device. Intel® Agilex™ I-Series SoC FPGA devices also integrate the quad-core ARM Cortex-A53 processor to provide high system integration.
The Intel® Agilex™ I-Series FPGA has options to integrate Compute Express Link™ (CXL™), an open standard interconnect protocol for high-speed CPU-to-device and CPU-to-memory. This standard is built on the PCIe physical and electrical interface.
The FPGA delivers up to 40% lower power for applications in data centers, networking, and edge computing.
FPGAs (field programmable gate arrays) are used to offer high-capacity logic and memory storage.
The system-on-chip (SoC) is an integrated circuit inside the FPGA, most often a CPU (central processing unit) processor and supporting peripherals, that provides more flexibility and integration, and allows the FPGA to better control the board.
Our Intel® Agilex™ board offers primary interfaces and components, such as 400 Gb Ethernet, PCIe Gen5 x16 (CXL™ compatible), HSI connectors (offering transceivers for PCI Express), power supplies, a USB 2.0 port (for JTAG, UART, BMC), high-speed transceivers, DDR4 (on-board and SO-DIMM) interfaces and more. These components are from Intel®, Micron Technology, Inc., STMicroelectronics, and Cypress Semiconductor.
The Agilex™ board has a full height, half-length, 2-slot PCI Express form factor, specially designed to fit into various servers and chassis available on the market, as well as custom rack systems for embedded applications.
The Peripheral Component Interconnect Express, commonly known as PCI Express, is a high-speed serial computer expansion bus standard. Our FPGA board offers up to three PCI Express x16 slots or two CXL™ standard interfaces. Added to an Intel® Agilex™ SoC FPGA I-series, this makes our board quick and efficient.
Reduce time to market of your next embedded project with our Agilex™ SoC board, using the Intel® Quartus Prime development tools. We draw on our firmware, hardware, and software skills, and full documentation package and reference designs to create our boards.
