Recent technological advances allowed the word to construct several wearable products that can capture and process the human body bio-signals. The PPG signal becomes one of the most contenders in heart rate monitoring due to their prominent features, flexibility, effectiveness and low costs. This paper present a novel System of PPG Heart rate calculation based on FPGA, using the Pan and Tompkins as...
This paper reports on the Field-Programmable Gate Array (FPGA) real-time implementation of a vector control scheme, by means of hardware-in-the-loop simulation. This approach will be applied for a PMSM used to propel an electric scooter, preceding its integration in a more complex experimental setup. The emerging need for powerful, flexible system-on-a-chip (SoC) platforms for developing complex drive...
Post-silicon validation is concerned for discovering design errors that escape to the silicon prototypes. Recent research efforts have shown how to reuse the constraints from pre-silicon verification to support post-silicon constrained-random validation. The objective is to subject the prototype to a large volume of random, yet functionally-compliant stimuli. In this paper, we present a new method...
As more electric aircraft power systems grow in complexity and power rating, the design, evaluation and testing of such systems become quite challenging tasks, while real-time simulator based hardware-in-the-loop (HIL) technique is considered a cost/time-effective solution. This paper applies RT-LAB to real time simulation for aircraft electric power system (EPS) with hardware Bus Power Control Unit...
USB has many features like plug and play, hot plugging, portability, etc. which are attractive in designing portable high speed data acquisition systems/PC peripheral devices. The paper describes the design of USB (FT2232H) based data acquisition (DAQ) system. ‘LabVIEW’ graphical programming environment used for real time data acquisition, processing and display. The details on design aspects of dynamic...
This work presents a back-to-back power converter Permanent-magnet Synchronous Generator (PMSG) wind turbine real-time simulation system based on FPGA Hardware-in-the-Loop (HiL) concept. The proposed system can be used for Electric Control Units (ECUs) evaluation in a real-time manner. The refreshing rate effect of a HiL emulator is discussed and analyzed with real-time simulation proof. Within this...
Time-predictability is an essential property of software components of safety-critical hard real-time systems. Single-path code generation produces code that forces every execution to follow the same trace of instructions, thus making the execution time of code independent of its input data. This supports the time predictability of components and simplifies their worst-case execution-time analysis...
Chroma-key is a robust and important technique for processing image or video. This technique gives immersive feedback on Video, TV production and weather forecast.

VLSI architecture is proposed for this method, which is implemented on FPGA based on K-means method...
The use of rapid prototyping tools such as MATLAB Simulink and Xilinx System Generator becomes increasingly important because of time-to-market constraints. In this paper, we consider Xilinx System Generator for software simulation and real time implementation on FPGA circuit of a pseudo-random number generator (PRNG) based on unified hyperchaotic system. For this purpose, we propose a new PRNG with...

We propose in this paper a new hardware architecture for implementing the hyperchaotic Lorenz generator using FPGA technology. The goal is to design a new complex chaotic system which can be used as an unidentifiable key generator in embedded cryptosystems. The proposed architecture provides good performances in terms of throughput and resources cost required for highly secure communications between...
When generating the verification stimuli in a pre-silicon environment, the primary objectives are to reduce the simulation time and the pattern count for achieving the target coverage goals. In a hardware environment, because an increase in the number of stimuli is inherently compensated by the advantage of real-time execution, the objective augments to considering hardware complexity when designing...
We propose ttCodeGen, a flexible code generation framework for potentially distributed, time-triggered real-time systems. It is designed for developing systems based on the Logical Execution Time (LET) programming paradigm which enables the platform independent description of the timing behavior of such systems. The ttCodeGen framework covers both code generation on node level as well as the generation...
