Processor blade with cPCI serial comms for high-speed data

May 03, 2016 // By Graham Prophet
Adlink Technology’s cPCI-A3515 is the first product in a series of CompactPCI Serial processor blades hosting . This new 3U module hosts an Intel Core processor and supports the CompactPCI Serial industry standard for applications requiring reliable high-speed, high-bandwidth data communications, such as railways, factory automation, and defence.

The PICMG CPCI-S.0 CompactPCI Serial standard, which evolved from the PICMG 2.0 specification, is the fastest, most versatile, most cost-effective open standard for CompactPCI (CPCI). The Serial standard is mechanically and electronically compatible with 3U and 6U euro-cards, defining an interface for high-speed switched fabrics with a star topology. Point-to-point connectors allow up to eight peripherals on one system slot without switches or bridges. Ethernet data transfer can be configured with full mesh topology, which allows up to 1000Base-T connections to all peripheral slots for redundant, safety-critical systems.


“Adlink offers cost-effective migration by providing a bridge adapter for existing CPCI I/O cards. An upgrade to the CompactPCI Serial standard on Adlink embedded modules requires only an upgrade to the new Serial CPU blades,” said Yong Luo, general manager of Adlink’s embedded computing product segment. Users can test the serial interface on their systems by using Adlink’s starter kit, which includes the CPU board, I/O cards, fanless chassis, backplane, and power supply.

The Serial standard extends parallel PCI with serial PCI Express, SATA, Ethernet, and USB, and supports transfer speeds up to 600 Gb/sec. cPCI-A3515 offers data throughput options with PCIe interfaces that include one PCIe x8, two PCIe x4, and three PCIe x1. Four 6 Gb/sec SATA interfaces and up to ten USB 2.0/3.0 ports are also available. Rear I/O features up to eight 1000Base-T Gigabit Ethernet connections to compatible backplanes, which may be either hybrid or CPCI 2.0/S.0 commercial-off-the-shelf. Front I/O includes two display ports, two USB 3.0, and two Gigabit Ethernet ports, as well as an option for two USB 2.0, one RS-232/422/485, and one VGA port.


The blade hosts a quad-core 4th/5th generation Intel Core i7 processor with up to 16 GB dual-channel DDR3L soldered ECC-type SDRAM. The QM87 chipset with AMO EFI BIOS and 128 Mbit SPI flash memory supports Microsoft Windows 7/8, Red Hat Enterprise Linux 6.6/7.0, Windows Embedded Standard 7, VxWorks, and
