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