Control
The RFT board has a local Digital Signal Processor (DSP) with an external EPROM.
The DSP performs multiple control tasks:
1.) It handles communication with the BEP over the VME bus.
2.) It updates filter coefficients and other parameters in the data path.
3.) When output events from the Front-End Controller is received, it sets up the PipeLink output control
for data tagging and transfer.
During transfer of time motion data, it sets up a
time-slot
data transfer (which replaced the output event
based transfer).
