To achieve the highest level of performance out of a SkyWriter system, an application must
take advantage of the Hyperpipeline configuration. A hyperpipeline takes advantage of the full
performance of both pipelines to drive a single display. The outputs of the two pipelines are
interleaved on a frame by frame basis by the built-in Pipeline Multiplexer (pMUX).
The PMUX is a daughterboard residing on the display board of Pipeline 0 and takes the RGB
output directly from Pipeline 0. The Pipeline 1 RGB output is wired back into the PMUX from
the outside of the front I/O panel behind the forward fascia. When the command is issued in
the software to switch the system into Hyperpipeline mode, the Pipeline 0 output will display
alternating frames from Pipeline 0 and Pipeline 1.
To take advantage of this feature, the application must draw one frame to Pipeline 0, then one
frame to Pipeline 1 and keep alternating to keep both pipelines full at all times. Thus a single
stream of frames is being split in two to travel down the separate pipelines, then recombined
into a single stream in the PMUX to provide one channel with the performance of two
