Research and Development in improving the optical camera communication (VLC) transmission methods (modulation, FEC, synchronization ...). MATLAB-based simulation platform for selecting suitable transfer methods. Deriving the requirements for smartphone app creation and setup CPLD-based demonstrator, the unidirectional transmission using OCC. VHDL is used for CPLD design.

Worked in Visible Light Communication. MachXO3 (Lattice CPLD) is used for programming. CPLD design is done in VHDL. Data bits are modulated according to the specific specification and send through RGB LED. Different CPLD design where done in different specification during the internship period based on Visible Light Communication. Additionally arduino C program was analyzed and developed in VHDL . Reverse engineering work was done (VHDL code was developed according to the output waveform).

• Arbeitete in der Kamera-basierten Anwendung für die Automobilindustrie • FPGA-basiertes Modul wurde für die automatische Belichtungskontrolle entwickelt • die Anwendung wurde in Zynq und MicroBlaze implementiert • Erfahrung in der Arbeit mit Xilinx SDK • I2C-Kommunikation wurde implementiert, um die CMOS-Sensor Registerwerte zu schreiben und zu lesen • Vivado Design Suite wird für die Entwicklung verwendet • Erfahrung im AXI-Bus und Interrupt-Handling

• RTL verification for ASICS and FPGA • Detecting bug in the design by running the test case • Understanding the test case written for microcontroller interfaced with FPGA (C language for microcontroller, Verilog for FPGA) • Vivado design suite is used to run the test case • Issue solved by simulation result and generated netlist

Comparision of Low cost FPGA families ( ECP5, ARTIX 7, CYCLONE V ) Project descriptionModelling of Calculator(VHDL) and implementation in FPGAs(ECP5, Atrix7, Cyclone V) Comparison of FPGA - Hardware & Simulation (ECP5, Atrix7, Cyclone V) Comparison of Design tools (Xilinx ISE, Lattice Diamond, Altera Quartus) Modelling of Barcode scanner(VHDL) Implementation of Digital stopwatch in VHDL (Modelsim 6.1d)
