The only advantage of UP is to support the Papilio Pro, but that port is also very limited in other ways and the Pipistrello provides a more reasonable platform that also supports AMP.
On the other hand, RPCs on UP are difficult to implement with the session.c protocol system (without an operating system or coroutines), along with many other minor difficulties and maintainance issues. Planned features such as watchdogs in the core device are also difficult on UP.
SplineSource() supports spline interpolating multi-channel tabular data,
cropping it and generating wavesynth compatible segment data from it.
ComposingSplineSource() needs some verification still.
Flash proxy is now searched in ~/.migen /usr/local/share/migen
/usr/share/migen and in the directory specified by "-d" argument
or in artiq/binaries/<board_name>/ if "-d" is not specified.
Once the Sequencer ack's a line, the Parser starts preparing the
next one. This includes jumping through the frame table if necessary.
To stall the Parser while the Sequencer executes the last line of a
frame and to ensure that the frame select lines can be set up and their
sampling is synchronized to a trigger, we add a triggered stall line
at the end of the frame.
When that line is triggered the Parser jumps through the table and starts
parsing the first line of the next frame. We let the duration of this
last stall line be 10 cycles (200ns@50MHz) to be able to distinguish this
sampling of the frame select lines from the triggering of the first line
in the next frame.
