  • Using the YM 2151 for Noise Generation

    Hi there FPGA lovers! Here we have another release of our series of YM2151 posts. To recreate the YM 2151 in FPGA using VHDL, every aspect of the YM 2151 needs to be mapped on to the recreation platform. However an interesting aspect regarding the YM 2151 is that it uses random values for generation…

  • Understanding the YM 2151- YM 3012 Relationship

    Hi FPGA lovers! In our conquest to find studio quality sound, we stumbled upon the YM 2151 FM Synth Chip which has been used by Yamaha from time immemorial in a number of their electronic keyboards and arcade games. The YM 2151 has a Digital output rather than an analog output and this makes it…

  • Create Studio Quality Sound with YM 2151 and FPGA

    Hello FPGA lovers! Today’s post is about making real studio quality music rather than the monotone buzzers from conventional circuits. FPGAs can be used to create monotone sounds such as beeps by using the right combination of DACs and buzzers. However these devices cannot be used to create studio quality sound that not only plays…
