    Description
    New DesignWare EV6x processors deliver up to 100X higher performance on common vision processing
    tasks than the previous generation EV5x vision processors to address high throughput applications
    such as ADAS, video surveillance and virtual/augmented reality. New scalable vector DSP architecture
    supports full range of vision algorithms for 1080p to 4K resolutions to meet high definition
    requirements. Programmable convolution neural network provides up to 800 MACs/cycle for fast and
    accurate object detection and 5X better power efficiency than other vision processors

    Synopsis
    * AXI VIP Integration for MLV environment and SLV Environment (UVM).
    * Worked on C-based verification, MLV test cases in C for TNN ASIP processors.(Dual Processor
    core). Enhanced thread management. Memory management with DMA-AXI transfers.
    * Worked on writing C test cases for SOC environment from scratch for ARC HS cluster (4 ARC
    processor +APEX for user interface).
    * Worked on Randomization to randomize the image pixel values, Convolution co-efficient for
    CNN engine.
    * Worked on checking the image processing algorithms.
    * Have good experience on handling the images in memory, Techniques involved in image
    processing to handle it for Convolution neural network.
    * Presently working on creating reference functions for verification using
    "CAFFE' model from Berkeley University.
    It involves giving generating the ".caffe model and .prototxt" file for "EVGENCNN" tool of
    Synopsys and testing them for randomized graphs, generate the Weights and graph with OPENVX
    library to test them in CNN ASIP engine. It is being done in both PLV, MLV, SOC level.
