System Interfaces

The Accelerator-6D board has the following system interfaces:

PCI Express (see page 22)

USB (see page 24)

JTAG (see page 25)

PCI Express

A PCIe connector is available for plugging the card into a host PC where the data is provided over the interface.
The Gen 3, ×8 interface supports 2 ×64 Gb/s throughput (64 Gb/s receive, 64 Gb/s transmit). The figure above
shows the dedicated PCIe pins on the HD1000, designated SerDes Bottom 0 – 7 in the figure. The table below
shows the pins on the HD1000 and their connections to the PCIe edge connector.

Note

Power is not supplied to the board via the PCIe connector.
