Simulation of MCU hardware peripherals
Bartosinski, Roman; Kadlec, Jiří
2007 - English
This paper describes one possible way, how MCU hardware peripherals (e.g. PWMs, Timers, ADCs, etc.) can be simulated in Matlab/Simulink environment and how code controlling these peripherals can be generated. The described implementation of the MCU hardware peripherals is based on using function call outputs as peripheral interrupts and external blocks called Methods as peripheral control functions. In the generated code by Real-Time Workshop, the Method block is represented by directly called corresponding function of the used periphery. Článek popisuje možný způsob simulace hardwarových periferií MCU (např. PWM, Časovač, ADC) v prostředí Matlab/Simulink. A způsob jak může být generován řídicí kód pro tyto periferie.Popisovaná implementace využívá signály funkčního volání jako funkce periferií. V generovaném kódu z RTW je speciální blok Method, který reprezentuje přímo volané funkce použitých periferií.

Design of Control Application Using Processor Expert Blockset
Stružka, P.; Waszniowski, L.; Bartosinski, Roman; Bysterský, T.
2007 - English
This paper describes design of a controller of the brushless DC motor using Processor Expert blockset in Mathworks Simulink. The controller algorithm is designed in Simulink and the Processor Expert blockset provides access to the microcontroller hardware through its Hardware Abstraction Layer. The behavior of the controller (including the peripherals represented by Processor Expert blocks) is verified by simulation. The Real-Time Workshop is used for the C source code generation from the controller model. Článek popisuje návrh řídicího systému bezkartáčového motoru s využitím Processor Expert blocksetu v prostředí Matlab-Simulink. Řídicí algoritmus je navržen v Simulinku a PE blockset poskytuje přístup k hardwarovým periferiím mikrokontroléru přes HAL. Chování řídicího algoritmu i s hardwarovými periferiemi je ověřena simulací. Zdrojový kód v jazyce C pro mikrokontrolér je vygenerovaný pomocí nástroje Real-Time Workshop.

Simulink Model Converter for Embedded Video Accelerator
Kovář, Bohumil; Schier, Jan; Zemčík, P.; Herout, A.; Zuzaňák, J.
2007 - English
An embedded DSP/FPGA system for accelaration of image or video processing, with a scripting-language-based configuration engine, pulling software modules or hardware blocks from function libraries, is considered. The Simulink environment is used for rapid application design for this system. The aspects of converting Simulink block diagrams into the scripting language for the configuration engine are discussed in the paper. Článek se zabývá vestavěným DSP/FPGA akcelerátorem pro zpracování obrazu nebo videa. Tento akcelerátor používá vestavěný konfigurační engine, ovládaný skriptovacím jazykem, který dynamicky zavádí předem připravené funkční moduly.

Asymptotic Analysis of Bias of FastICA-based Algorithms in Presence of Additive Noise
Koldovský, Zbyněk; Tichavský, Petr
2007 - English
The idea that common blind techniques based on Independent Component Analysis (ICA) behave in noisy environment like a biased MMSE separator (sometimes called Maximum Ratio Combiner (MRC)) was introduced in our recent work [3]. In this paper, we put this in more precise terms by doing an analysis of the bias of approaches that are based on known ICA algorithm FastICA. We show that the one-unit approach is the best MMSE estimator in terms of the bias. Myšlenka, že se většina metod pro slepou separaci signálu používajících analýzu nezávislých komponent chová jako vychýlený MMSE estimátor byla použita v naší nedávné práci [3]. Zde tuto myšlenku konkrétizujeme tím, že analyzujeme odchylku algoritmů, které jsou odvozené ze známého algoritmu FastICA. Je prokázáno, že varianta one-unit je z hlediska vychýlení nejlepší MMSE estimátor.
