sult, ADL was able to move the SisTrO
project from the testing stage to a fully
functional solution in less than nine
months.

sues prevented the pursuit of such an
elegant solution, leading to the decision to use a recording camera. The
recording camera could transmit test
point data to an image processor after
each test point, i.e., store release, but
the performance level possible with Gigabit Ethernet cannot match this application's real-time requirements.
Upon the first contact with ADL's
team, IPEV researchers were impressed
by ADL's ability to listen and truly understand their needs.
ADL suggested the use of the CXL-6
frame grabber by EURESYS, an interface
card compatible with the ADL processor
that supports the CoaXPress protocol,
to transport the image frames between
the camera and the ADL processor.
Using this innovative hardware platform solved the technical issue of freezing the processor configuration. As a re-
