Publications

  • Hardware/Software partitioning algorithm for embedded systems with repeated functionalities

    IEEE

    2008

    We proposed a hardware software partitioning algorithm which would consider redundant functionalities/work-blocks in a embedded system and accordingly give an optimized hw/sw partition the system. Most of the research is done considering each block as unique, whereas in real life cases workflow of all systems has functionalities being re-used over and over again.

Projects

  • Comparative beta diversity analysis of functional genomics in amphibian skin microbiomes

    February 2013 – May 2013

    Analyzed 16S RNA data from amphibians to enumerate host-microbe-pathogen relationships using the Quantitative Insights Into Microbial Ecology software package. Compared PCA and LLE dimensionality reduction techniques to visually determine the effect of pathogens on the immunity of amphibians.

    • Narasimhan Madabusi
  • Time Lapse Video – Embedded Systems

    Implemented a USB image capturing system using Linux on a TI Beagleboard. The images were captured at every 1 sec interval in YUV format, sharpened, converted into PPM format, and stored on an SD card. And finally, ffmpeg was used to create time lapse video. – Producer/Consumer bounded buffer problem – Used semaphore and mutex locking on buffers between Image Capture (Producer) thread and Sharpening (Consumer) thread Resources/Technologies : C, Linux, TI Beagleboard

  • Speech Recogition

    This project was a subpart of a project to actuate a robotic arm to pick coloured balls and drop them in coloured bins upon receiving a speech stimulus. I incorporated the MFCC library to capture the feature vectors and implemented the k-means clustering to identify the spoken word is Red, Green or Blue. Technology : C

    Team Members (1):
    • Krishna Chaitanya
  • Music Categorization by Genre

    Retrieved features (MFCC) from songs, implemented Locally Linear Embedding (LLE) dimensionality reduction technique, and used SVM for classification of songs by genre. Resources/Technologies : Matlab, and LIBSVM toolboxes

  • ANOVA of Cache Coherency Protocols in Gem5

    Collected statistics of execution times of workloads in SPEC 2000 suite for different coherency protocols (MESI, MOESI) for a given cache configuration and performed Analysis of Variance and TukeyHSD to determine the better protocol. Resources/Technologies : R, Gem5, SPEC 2000 suite (integer workloads)

    Team Members (1):
