The Virtex UltraScale+ (VU13P / VU11P / VU9P / VU7P / VU5P) Switch Profile category refers to embedded computing hardware—typically designed in the 3U VPX form factor and aligned with standards like VITA 65 (OpenVPX) and SOSA™ (Sensor Open Systems Architecture).
Instead of acting solely as a processing node or payload card, a board built on a Switch Profile (e.g., SLT3-SWH-4F1U7U1J-14.8.7 or SLT3-SWH-6F1U7U-14.4.14) is configured to act as the high-speed interconnect hub within a multi-card VPX chassis.
In OpenVPX architectures, slot profiles define the specific pinout and signal routing on the backplane connectors (P0, P1, P2):
-
Payload Profile (
SLT3-PAY...): Designed for target processing modules (SBCs, DSPs, standard FPGA accelerators) that process raw sensor data. -
Switch Profile (
SLT3-SWH...): Designed for the central communication routing module. It manages:-
Data Plane Switching: High-bandwidth packet transfers between payload slots (e.g., 10G/40G/100G Ethernet, PCIe Gen3/Gen4).
-
Control Plane Switching: System management, health monitoring, and lower-speed signaling across slots (e.g., 1G/10G Ethernet, IPMB/VITA 46.11).
-
Expansion Plane / Optical Interconnects: Routing off-board data streams via VITA 66/67 optical/coaxial aperture connectors (e.g., MT Ferrules/FireFly interfaces).
