17th LSI Design ContestsEin Okinawa  Design Specification - 4

4.Contest Design Target

In this specification, we have used Synopsys: Symphony Tool but you guys can use any design tools and language.


  • Level 1 : For beginner
  • You are supposed to implement the Spectrum Subtraction Algorithm as explained in Chap.2 by software. A FFT hardware can be obtained by EDIF file so that you do not need to design RTL as far as you use this hardware EDIF file. As explained in this document, we offer a sample program which just get sound data by ADC, then it goes through CPU and then it is output to DAC. You may modify this sample program.


  • Level 2 : For Intermidiate level student
  • Any type of modification is welcomed as far as you implement a noise canceller. It is totally free design topic! For example, you may implement other types of algorithms by software or you may speed up hardware FFT something like that.


    Do your original work!
