As the heaviest particle of the Standard Model, the top quark is a key ingredient in both precision electroweak physics measurements and searches for new physics models. In this thesis are presented single- and double-differential cross-section measurements for the production of top-quark pairs in the resolved topology of the all-hadronic channel, using data collected by the ATLAS detector at the CERN LHC. Future prospects for the application of machine learning algorithms for the reconstruction of the ttbar all-hadronic system are also presented and validated. This thesis also includes work related to the upgrade program of the ATLAS trigger and data acquisition system for the High-Luminosity LHC. In particular, studies for the development of the hardware tracking for the trigger are presented.
