GPEX-AS is a highly flexible and configurable
end point controller IP targeted for both PCIExpress
and Advanced Switching technology implementations
in compute and communication applications. GPEX-AS
is part of GDA's PCIExpress (GPEX) family of
IP solutions, which includes End Point (GPEX-EP)
and Root Complex (GPEX-RC) designs. GPEX-AS
supports both PCI-Express and AS protocols.
It supports PCI-express end-point and root complex
functions, and AS port controller logic for
a wide range of applications such as native
AS node, leaf bridge, root bridge and switch.
The controller architecture is tailored to address
the needs of different market segments with
highly configurable system PIs and support for
PI-8, SLS, SQ and SDT. GPEX-AS architecture
offers High performance, High link utilization,
Low latency, Low power consumption and Small
silicon footprint. It's simple, configurable,
layered architecture is independent of application
logic, PHY designs, implementation tools and
the target technology.
It can be easily used in FPGA, Gate Array and
Standard Cell technologies optimally.
