  Literature Survey Introduction :There are various devices which are used for the computations like microprocessor, ASIC . These devices are very expensive to buy , so we will give preference to FPGA Similar Topics :  Microprocessor- It is a used for doing different calculations in several devices  ASIC(Application Specified Integrated Circuit)- It is application specified which may can vary with different app’s

   In abovediagram, FPGA consists of CLB’S, I/O blocks ; Which are connected each other  These CLB’s are connected to each other for different operations  The i/o blocks may take different forms like input block, output block, can take both input & output  Input is passed to the i/o block & inputs are passed to logic blocks for further operations  Generated o/p is given to the i/o block & its is passed to connected device for further calculations
