Constructing Test Suites for Real-Time Embedded Systems Under Input Timing Constraints

open access: yesIEEE Access, 2019
Testing of real-time embedded systems (RTESs) under input timing constraints is a critical issue. Models which can specify timing constraints have respective merits and demerits and test suites which can cover more input possibilities and detect more ...

Feedback computability on Cantor space

open access: yes, 2019
We introduce the notion of feedback computable functions from $2^\omega$ to $2^\omega$, extending feedback Turing computation in analogy with the standard notion of computability for functions from $2^\omega$ to $2^\omega$. We then show that the feedback

HIGH-SPEED MULTIPLIER DESIGN BASED ON AN OPTIMIZED PARALLEL PREFIX TREE ARCHITECTURE

open access: yesInternational Journal of Advances in Signal and Image Sciences
Multiplication is a fundamental arithmetic operation, central to the performance of arithmetic and logic units (ALUs) in nearly all electronic systems. As such, the design and optimization of multipliers play a crucial role in improving the efficiency of

Model Based Safety Analysis with smartIflow †

open access: yesInformation, 2017
Verification of safety requirements is one important task during the development of safety critical systems. The increasing complexity of systems makes manual analysis almost impossible.

Syntax-driven program verification of matching logic properties

open access: yes, 2015
We describe a novel approach to program verification and its application to verification of C programs, where properties are expressed in matching logic.

Using boolean circuits for the parallel computation of queries

open access: yesJournal of Computer Science and Technology, 2001
We present partial results of a research project in which we use boolean circuits as a parallel computation model for the expression of queries to relational databases.
