The MP7 and CTP-6: multi-hundred Gbps processing boards for calorimeter trigger upgrades at CMS

Test results are presented for two AMC cards, the ``CTP6'' and ``MP7''. The two cards take different approaches to connectivity: the CTP-6 has fully-populated backplane connectivity and a 396 Gbps asymmetric, optical interface, whilst the MP7 instead favours a 1.4 Tbps, symmetric, all-optical interface. The challenges of designing the MP7 card necessitated the development of several test cards; the results of which are presented.
