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.
