top.cpp @ 1016

Last change on this file since 1016 was 957, checked in by cfuguet, 10 years ago

Introduce a SocLib? platform implementing the FPGA mono cluster platform

This mono cluster platform is the one used for NetBSD and Linux on TSAR demonstrators.

It is based on the LETI platform but it contains an internal ROM and all the DSPIN routers have been removed.
