Created a snake game implementing a System on a chip with Programmable Hardware and a Soft Processor on the Altera DE1 Cyclone V board. The logic of the game was embedded in the fabric while Nios II Soft processor controls the game start and reset functionalities. My individual contribution was developing the logic for the game in Verilog and integrating the VGA display.

My individual contribution was developing the logic for the game in Verilog and integrating the VGA display.
Used Altera system integration tool for communication between the soft processor and FPGA fabric and Eclipse IDE for the creation of application software and Board Support Package (BSP). The game takes inputs from a PS2 keyboard to navigate the snake and displays the output on a 640X 480 VGA screen. Used QuartusII and Verilog to implement the project.

Implemented a FIFO with full and empty signal generators on the Dual-core ARM Cortex-A9 (HPS) of Altera DE1 Cyclone V board. Created a Linux Boot SD Card with an image file and booted it on the board. Used Qsys for communication between the HPS/ARM and the FPGA fabric. The output of the FIFO is fed into a counter whose output controls the LEDs on the board. The FIFO and counter were programmed in C in Linux and linked to the LEDs on the board.

Designed and implement a circuit for a real time clock on the DE1SoC Board. The clock can operate in two modes. In the emergency mode, after every 5 minutes, a SOS signal coded in Morse code is displayed on the LED. In the normal mode, it can function as a stopwatch. Once the clock is stopped, the time on the 7 segment display freezes and blinks until the clock is reset to act as a real-time clock again. Used QuartusII and Verilog to implement the project.

Collaborated in the programming and designing of a wheel chair capable of operating in two modes; automated and gesture controlled. Automated mode took user inputs from an on-board LCD in the form of current and destination points on a per-installed location specific map, while the gesture controlled mode used infrared proximity sensor to decode the hand gestures pertaining to Right, Left, Straight movement. Arduino Development Platform was used to carry out the programming of ATMEGA-32 to… Show more
