Projects
RTOS FOR AN ARM-M4F CORE RTOS, NVIC, STACK
- Designed a real-time operating system with an option to switch between co-operative and pre-emptive system, that supports round robin and priority scheduling, task synchronization using semaphores.
- Implemented a shell interface over UART for real-time profiling of the scheduler.
PEER TO PEER COMMUNICATION SYSTEM C, ASM, TM4C123GH6PM, UART, CCS
- Developed an interrupt-based communication system using M4F ARM microcontroller (TM4C123GH6PM) with a user interface, transmit/receive user-defined commands over UART on the RS-485 link.
- Implemented firmware to support features like acknowledgment, carrier sense, binomial backoff retransmission technique and sending back unsolicited messages to the transmitter.
- Implemented circular buffer to print out the messages on the serial console as part of UI programming.
DESIGN OF A 32-BIT RISC PROCESSOR INSTRUCTION SET, HAZARDS
- Designed a 32-bit scalar RISC microprocessor with load-store architecture, a 4-stage pipeline and Pseudo Harvard architecture including the instruction and data memory interfaces, register interface, and the entire pipeline control logic with full resolution of all structural, control, and data hazards.
BEST ARCHITECTURE FOR A CACHE CONTROLLER CACHE ARCHITECTURE
- Implemented a software program replicating the cache memory operations to speed up microprocessor system for FFT algorithm execution. Implemented write back and write through types of write strategies with LRU (Least Recently Used) replacement strategies for calculating average memory access time determined the combination of burst length, ways of associativity and write strategy gives the best performance.
