Correlator board DSP software
The correlator board DSP software is originally developed at Haystack. The software supplied to
Astron was the actual software in use there. However for the Astron/JIVE application
this was not sufficient. Therefor several changes have been made to this
software. Among others the error message handling to the host has been changed
and several parts have been optimized.
Recently the software was split in two separate projects, one for the processing DSP
and one for the IO DSP. The reason for this was that the a single project for both
DSPs brought up problems maintaining the code and it also poluted the final object
files.
Processing DSP
The main task of the processing DSP is the interfacing to the VME bus controller and
to control the IO DSP.
IO DSP
The main function of the IO DSP is read out the correlator chips and transfer the
data to the processing DSP.
