In this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be ...

− A new simple method of single soft fault detection and localization of analog parts in embedded electronic systems controlled by microcontrollers is presented. In the pre-testing stage of the method a fault dictionary is created based on the map of localization curves. In the measurement stage the time response to a stimulating square impulse of the analog part is applied to the input of the ...

We propose an architecture for implementing discrete-time control algorithms on a non-real-time operating system so that sensing and actuation occur at precise times, even if the OS preempts the control task. The architecture has the controller perform its computation on one processor and its sensing/actuation on a separate microcontroller. The controller sends arrays of future time-stamped act...

Embedded microcontrollers are highly constrained in cost, power and area. Therefore it is important to reduce the microcontroller die area. This will increase the amount of die per wafer and eventually increases the die yield in the microcontroller production. In addition, decreasing the size of program memory, a major part of the embedded microcontroller, will also reduce the die area for on-c...

Electromagnetic flow meters based on the principles of Faraday’s laws of induction have been used successfully in many industries. The conventional electromagnetic flow meter can measure the mean liquid velocity in axisymmetric single phase flows. However, in order to achieve velocity profile measurements in single phase flows with non-uniform velocity profiles, a novel Imaging Electromagnetic ...

The increasing interests in using renewable energies are coming from solar thermal energy and solar photovoltaic systems to the micro production of electricity. Usually we already have considered the solar tracking topology in large scale applications like power plants and satellite but most of small scale applications don’t have any solar tracker system, mainly because of its high cost and com...

Cooperation of the analog and digital circuits and the embedded controllers as well as their industrial use and technical application has always been in the focus of my interes. In reconfigurable systems the effectiveness and quality of the analog circuit system can be maintained and modified by circuit or by changing the single element values. There are further advantages of the programmable a...

A method for model checking of microcontroller code is presented. The main objective is to check embedded C code including typical hardware specific ingredients like embedded assembly statements, direct memory accesses, direct register accesses, interrupts, and timers, without any further manual preprocessing. For this purpose, the state space is generated directly from the assembly code that i...
