Not in this case. The onboard processing of data from the sensor suites was a Beowulf-style cluster of mobile phone ARM systems. All the computing hardware was carefully selected and engineered to be extremely frugal with power.

Which is why I found it ironic that the software architecture was done in an overtly wasteful "throw hardware at it" style. Some basic attention to software performance engineering could have increased efficiency by an integer factor. It was quite the contradiction.
