Abstract
This paper introduces the method that applying FPGA chip and VHDL to design the
control system of microwave ovens. The system uses VHDL to fulfill the function of each
bottom module and the design of the top layer pleted via graphic entering. This
paper mainly illustrates the idea of module design and description method of state chart
and that their application in VHDL and simulation results in the develop system of Quartus
II.
Microwave controller system is a utility-type system that includes not only the
function of simple operation, but also good effect of cook. According to fixed routine, you
can cook some homely dish via taking different time and different level firepower to heat,
and this can not only save time, but also save energy. It mainly includes a couple of
modules as follows: input module, control module and display module. Input module
fulfills key-press scanning and keyboard decoding, control module includes status
switching control, data loading, cook time, temperature control, sound effect tip and so on,
display es down to display coding decipher and the flashing of indicator light.
Through the analysis of requirement, detailed function design, coding, module
connection, using FPGA to fulfill relevant function. Through waveform simulation,
download debugging, it verifies the feasibility of the design and the effectiveness of
realization method and basically fulfill the requirement of the system.
