This book covers 28nm, 40nm, 65nm and 90nm FPGA based design along with energy efficient techniques Junction Temperature Controlling, Stub Series Terminated Logic, Low Voltage Complementary Metal-oxide Semiconductor, High Speed Unterminated Logic, and output load Capacitance Scaling. Along with FPGA, this book also deals with Arduino accelerometer and gyroscope. Along with 7 FPGA based projects, this book also has two arduino based projects. One is Gesture controlled robotics Arm and Other is night vision Robot. In FPGA project, we write Verilog code of Router, Data Encryption Standard algorithm, Cyclic Redundancy Check and Light Dependent Resistor.
