System Specs and Features

Works with any current BittWare PCIe board

Crosspoint switch fabrics

Independent cross point switch fabrics simplify configuration:

  • Data can flow from port-to-port without entering the FPGA
  • Copy data to the FPGA without interrupting the data flow
  • Independent switch fabrics for 25G and 10G

CPU Support

The e4 system is equipped with a range of CPU options:

  • Management is built-in as separate device
  • COM Express Type 10 or Type 6 built-in; requires no software
  • Connected to the board via PCIe lane x1 and USB
  • USB access to the BittWare tools for board managment

BittWare BittWorks Toolkit and BMC

The e4 system allows easy access to BittWare’s software tools and Board Management Controller (BMC):

  • Remotely program the FPGA over USB, erase it, and program the flash
  • Monitor board power and temperature and re-program the onboard clocks
  • Set points to shut the board down when it gets too hot or draws too much power
  • Access JTAG over USB (if supported by the board)
  • Remote access to all software tools and BMC features

Built-in Tools and Remote Operation

Built-in software tools allow remote operation:

  • Vivado tools and Ubuntu 16.4 pre-installed
  • Windows supported
  • FPGA board is configured on the fly; the system freezes the last known good configuration

Advanced Power Features

Have precise control over your system with advanced power features:

  • Turn off PCIe separately—uncoupled from system
  • Precision power monitoring of the FPGA board: program thresholds and connect them to system fans
  • Load-shared redundant power supplies on the e4 base board

Precision clock source

A 100 MHz on-board clock can be used as PCIe reference clock or as a very high precision internal clock:

  • 100 MHz oven-controlled crystal oscillator (OCXO)
  • 5 or 10 parts per billion accuracy
  • Clock multiplexer
  • Timestamping support

Rapid Start-up

Unlike a standard server, the e4 can boot quickly, getting the FPGA image loaded once power is up:

  • 1 sec boot time
  • Configuration is stored on the base board and does not require COM Express

Two e4 boxes can fit back-to-back in a 1U space

Short Depth

The e4 is small enough to fit two devices in one rack:

  • 1U chassis
  • 12” depth

Additional Interfaces

Additional interfaces connect directly to the Linux machine that are ideal for a networking device:

  • Micro USB, display board, OOB port, USB, and Ethernet
  • Allow access to command line, firmware upgrades, GUI port monitoring
