49 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
50 You can operate a Linux system on this board by using an M32R
51 softmacro core, which is a fully-synthesizable functional model
52 described in Verilog-HDL.
53
54 The Mappi-I board was the first platform, which had been used
55 to port and develop a Linux system for the M32R processor.
56 Currently, the Mappi-II, an heir to the Mappi-I, is available.
