Sankalp Semiconductors Pvt Ltd, Mixed Signal Layout Design intern Jan – Dec2015

• Lead the team which carried out MS layout design and verification of Phase locked loop circuits.

• Designed and developed an innovative architecture and layout design of an ALU with the least silicon areas.

• Worked on several other individual mixed signal and digital layout design projects (BGR, multi stage amplifiers, power management circuit).

Technical Purview

Languages: C, C++, x86 Assembly, Python, Java, CUDA, OpenACC, VHDL, Verilog. Software Tools: GNU Toolchain (GCC, binutils, GDB), git, QEMU, Gem5, MATLAB, Xilinx Vivado, Xilinx SDK Microcontrollers: TI MSP430, Renesas RX63N, Raspberry Pi, Beagle-Bone, Zynq-SOC Miscellaneous: Linux, POSIX threads, freeRTOS, Android, I2C, SPI, UART, USART, CAN, TCP/IP, JTAG Academic Projects

JOS Kernel Development, (UNCC)

• Built a primitive operating system on which simple commands can be run on our own shell and had UNIX like functions (e.g., fork, exec). It was implemented in an exokernel style for a X86 architecture emulated by QEMU.

• Used QEMUs debugging facilities to investigate the BIOS and boot loader of IA-32 compatible computer.

• Implemented memory management and paging mechanism.

• Wrote handlers to implement system calls and implemented round robin scheduler for pre-emptive multitasking for a multiprocessor system. Support for hardware clock interrupts and inter process communication was also added.

• Implemented a simple read/write file system to implement a library call that loads and runs on-disk executables. Real Time Priority Based Pre-Threaded Image Processing Server, (UNCC)

• Developed an image processing echo server which was based on a producer consumer model which interacts with the client through pool of worker threads.

• POSIX threads were used for preemptive thread execution and synchronization of operations that were derived from the OpenCv library.

Reducing File system latencies using Chopper tool, (UNCC)

• Examined ext4 file system’s block allocation using a tool called chopper. Four internal design issues were identified which caused significant tail latencies in file system operations. 1) Randomness-(due to scheduler dependency), 2) Allocation of last chunk, 3) File size dependency, 4) Sparse File-Normalization bug.

• Introduced bug fixes for the issues and demonstrated that there can be a 10% decrease in tail latencies. Self-Driving Wagon, (UNCC)

• Designed and developed a prototype of a self-driving wheel chair for the disabled to navigate inside buildings.

• PocketSphinx speech recognition engine was used to build the voice activated interface for the chair.

• ARIA API was used for map localization of the plan and design of the building floor plan. Network Interface Card driver for x86 exokernel for Intel E1000(82540EM), (UNCC)

• Developed routines for detecting the devices connected to the PCI bus. Mapped device registers to MMIO memory.

• Setup the DMA descriptors and queues to read and write data directly from memory without CPU intervention

• Developed a system call interface for user program to transfer and receive packets. Programming bare-metal ARM with QEMU, (UNCC)

• Bare metal C programming on ARM processor using GNU Linker scripts and QEMU emulator.

• Cross compiled and booted Linux kernel with BusyBox file system on the target hardware using UBoot.
