Abstract: An 8 bit micro-controller is made,simulated and tested on QUARTUSII by means of a top-down and modular design method based on the integration of FPGA and VHDL.The micro-controller has 30 instructions which are divided into 4 categories of data transmission,arithmetic and logic operations,process control,input and output.The simulation result shows that the 8 bit micro-controller can implement the instructions correctly in the frequency range of 100 MHz.
