SpaceVPX
Roth's presentation also notes that
" VITA 78.0 tailors OpenVPX to Space
applications, " and goes on to mention
that " SpaceVPX is not as expansive as
OpenVPX, but still unmanageable from a
board vendor perspective. " In a follow up
interview with Alpha Data CEO Adam
Smith, he expanded on this perspective.
" SpaceVPX becomes unmanageable
due to the wide range of communication
and signaling standards supported
across the power, data, expansion, and
control planes. While this adds flexibility,
it makes interoperability challenging.
Especially the " user defined " options,
which pretty much guarantee incompatibility.
This is typical of VPX standards.
You can see similar efforts in the embedded
defense markets with organizations
like SOSA consolidating OpenVPX, "
Smith said.
Further, Smith describes the AMD
XQR Versal AI Core VC1902 and Versal
AI Edge VE2302 ACAP devices as
In August 2023, Pixus Technologies introduced
an OpenVPX chassis platform that supports both
SpaceVPX and OpenVPX 3U processing boards.

enabling a step-increase in processing
capability for SWAP-constrained platforms.
" This technology is enabling the
next generation of adaptable data processing
in space. Versal is designed to
enhance on-board processing for payload
applications, boasting a significant
boost in compute density for vector-based
algorithms, and significant
data throughput increase compared to
earlier space devices. These devices feature
a processing sub-system, hard-wired
peripherals, and a platform controller
that enable seamless on-orbit reconfiguration
and mitigate single-event upsets
(SEU) effectively, " Smith adds.
As NASA and other space agencies,
OEMs and systems integrators continue
to design next generation spacecraft avionics
systems, the ongoing revision of
SpaceVPX and government/industry
adoption will continue to be a design
trend to watch across the embedded
computing world.
