	Improvement of the RISC-V CPU for the automotive industry Gallo, Jiří ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor) Cílem této práce je úprava existujícího RISC-V procesoru pro použití v automobilovém průmyslu - konkrétně ovládání motorů. Tyto úpravy jsou založeny na ukázkovém kódu pro řízení motoru využívajícím aritmetiku s pevnou řádovou čárkou. Tento kód byl profilován a analyzován, na základě čehož byly vytvořeny nové instrukce. Vliv těchto instrukcí byl zanalyzován jak z pohledu zrychlení běhu, tak z pohledu dopadu na parametry procesoru. Detailed record
	Optimal state estimation of a navigation model system Papež, Milan ; Havlena, Vladimír (referee) ; Dokoupil, Jakub (advisor) This thesis presents an investigation of the possibility of using the fixed-point arithmetic in the inertial navigation systems, which use the local level navigation frame mechanization equations. Two square root filtering methods, the Potter's square root Kalman filter and UD factorized Kalman filter, are compared with respect to the conventional Kalman filter and its Joseph's stabilized form. The effect of rounding errors to the Kalman filter optimality and the covariance matrix or its factors conditioning is evaluated for a various lengths of the fractional part of the fixed-point computational word. Main contribution of this research lies in an evaluation of the minimal fixed-point arithmetic word length for the Phi-angle error model with noise statistics which correspond to the tactical grade inertial measurements units.
