Contributions to the 7th workshop on Digital Backend Implementation: HW vs. SW:
Talk: "A Soft-Hardware balanced multiprocessor environment for flexible high data rate handling"
A new envision in the backend processing stages is possible due to the good compromise it can be achieved between hardware and software sharing duties. The simplification that can be obtained with a software solution with respect to the hardware implementation is indeed today achieved with an appropriate choice of those functionalities that can benefit from a balancement between developing time and complexity. A completely new solution can then be obtained with promising benefits. This approach is described for the first implementation under development.
Poster: "Fixed Multi-band Configuration for DBBC"
The DBBC system is a flexible backend for radio astronomy and in particular devoted to VLBI observations. Together with the observation method at present adopted in the astronomic and geodetic networks that provides the possibility to generate independent data channels in both bandwidth and tuning capabilities, it’s also possible to adopt a fixed multichannel configuration, where tuning bases are fixed and the bandwidth equal for all the produced channels. Such configuration requires reduced calculation resources and so allows to greatly reduce the hardware costs.
