  57          The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
  58          You can operate a Linux system on this board by using an M32R
  59          softmacro core, which is a fully-synthesizable functional model
  60          described in Verilog-HDL.
  61
  62          The Mappi-I board was the first platform, which had been used
  63          to port and develop a Linux system for the M32R processor.
  64          Currently, the Mappi-II, an heir to the Mappi-I, is available.
