2.6.1.5 High Speed Nt (ZBT) Memory

There is just over 8Mbytes of high speed, no turnaround, (Nt) SRAM is connected to
the FPGA allowing high speed data storage capability to FPGA cores that require
external memory. The memory is based on two separate

Samsung K7N321801M

devices which are each 2M by 18-bit devices, allowing independent access of each
device
Please contact us if you require further information on using this device.

2.6.1.6 SLB

Interface

The Sundance LVDS Bus (

SLB

) is a dual-port parallel interconnection link that is

capable of supporting data transfers at up to 700 MHz. Each port can be assigned
with a 16-bit differential bus, a clock and an over range differential lines.
The SLB is a link for data and clocks but also for control signals; it is based on a
Samtec QSH/QTH-DP series (0.5mm pitch) connectors.
The use of the SLB means that other customer specific input or output methods can
be supported without the need for re-design of the hardware. Some examples of IO
interfaces are listed below.
