Excalibur Device Overview
The EPXA10 development kit provides a powerful platform for
designing embedded processor PLD solutions. The kit features the
EPXA10 device, a member of the Excalibur family with an
ARM922T-based processor subsystem tightly coupled to the PLD
fabric. The EPXA10 development kit delivers flexible debug and
trace facilities to support the system under development, connection
cables and a full complement of software solutions including SOPC
Builder to generate the system, utilities and resource material,
third-party demo and evaluation software and documentation. The
development kit is the ideal development platform for complete
SOPC designs based on Excalibur devices for both ASIC prototyping
and low-to-moderate volume production runs.
Figure 7 on page 15 shows how the Excalibur device and other
elements can be integrated in an application. In this example, the
Excalibur device is configured for a voice-over packet gateway
application. The elements of the embedded processor stripe, PLD
modules, and off-chip peripherals are clearly identified.
