The main aim of the project is to compare the variations in execution time of an Intense Computing Algorithm in Software (PL-Program Logic) and RTL (PS-Processing System). This is done by simulating and synthesizing a chosen algorithm (here we have chosen the Sobel Edge Detection Algorithm) in Xilinx Vivado HLS 2015.3 design suite. In the initial phase the C++ code for the Sobel Edge Detection is developed in Xilinx Vivado HLS. The source code is then simulated using the test bench and the execution time is evaluated. The second phase involves developing the RTL part of the algorithm. This is done by the method of High-Level Synthesis (HLS) in Xilinx Vivado HLS. The RTL counterpart thus generated is then simulated and the execution time is calculated. The execution time for both the PL and PS implementations are compared and analyzed.
