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. | |
