Concurrency Containers
- Engineered concurrent data structures in C++, including single global lock (SGL) stacks/queues, Treiber stack, and Michael & Scott (M&S) queues, with a focus on optimizing performance across various threading models.
- Enhanced concurrent algorithms by implementing elimination and flat-combining techniques to increase throughput and also dealt with garbage collection.
- Developed concurrency primitives, including various locks and barriers, leveraging memory order techniques and C++ atomics to ensure thread-safe operations.
- Executed a comparative analysis of synchronization mechanisms utilizing the perf tool, yielding critical insights into performance trade-offs and system behavior under concurrent execution.
NanoVision AI
- Executed a sophisticated AI and computer vision project using NVIDIA Jetson Nano 2GB Devkit, Yocto BSP, and NVIDIA’s NGC Docker container registry, focusing on people count analytics in a defined area. The project entailed configuring a Yocto-based OS image, enhancing it for DeepStream AI capabilities, and deploying the image on Jetson Nano hardware.
- Developed and tested Docker containers for AI applications, demonstrating expertise in embedded systems, Docker, AI model deployment, and computer vision. Incorporated a feature to track the number of people crossing a virtual line, updating both cumulative and per-frame counts within the object metadata.
- Utilized Yocto Project for tailored OS image development and showcased hardware-software integration skills for AI applications, with an added functionality to verify object movement against a pre-set direction and line crossing events in real-time.
8051 Microcontroller Bring Up
- Constructed a board using the 8051 microcontroller and gained in-depth knowledge of 8051 simulators and debugging, including register manipulation, data memory editing, and breakpoint management.
- Demonstrated proficiency in logic design and hands-on experience with hardware components such as power-on reset, voltage regulators, clock circuits, and RS-232 connectors, ensuring proper functionality and memory management.
Socket Server Development for Embedded Linux
- Developed a socket server (aesdsocket) in C for embedded Linux, enabling TCP/IP networking, signal handling, and daemon operation, deployed on a QEMU virtual machine.
- Applied thread synchronization with mutexes and managed threads via a custom linked list, achieving data integrity and efficient handling of concurrent operations.
- Integrated time-stamped logging, with precise synchronization across threads using mutex locks, to maintain accurate records of server-client interactions.
- Testing and validation within an embedded Linux framework, employing Bash scripting for automation and Valgrind for memory integrity checks.
