3. Expansive Connectivity for Real-time

IoT is ever-growing and requires immense amounts of connectivity. This generation of low-power high-performance processors offers support for:

  • 3x 2.5GbE LAN
  • PCIe 3.0 (up to 8 lanes)
  • USB 3.1 (up to 4 ports)
  • USB 2.0 (up to 10 ports)

System integrators and OEM designers can now provide further additions to time-sensitive network-enabled MACs for real-time data analytics with 2.5GbE LAN; compared to previous generations that are limited to 1GbE LAN. As IoT data becomes more complex, there will be a demand for faster data transfer speeds. The upgrade in USB generations enhances data transfer speeds with USB 3.1 offering 10Gbps transfer rates, while USB 2.0 offers 480Mbps. IoT sensors and devices that utilize a USB connectivity benefit from this enhancement as some IoT are bottlenecked by USB 2.0 data transfer rates. Industrial IoT applications are limited by the lack of edge AI support in space-constrained locations.

The introduction PCIe 3.0 paves way for edge AI workload consolidation through distinct types of hardware accelerators. Industrial computers now have the capabilities to support AI inferencing for machine vision and smart kiosk machine applications in much smaller form factors. When compared to Bay Trail, Elkhart Lake processors have double the amount of PCI Express Lanes and utilize PCIe 3.0 with bandwidth speeds of 1GB/s per lane versus PCIe 2.0 at 500MB/s per lane.
