67 | The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping. | |
68 | You can operate a Linux system on this board by using an M32R | |
69 | softmacro core, which is a fully-synthesizable functional model | |
70 | described in Verilog-HDL. | |
71 | ||
72 | The Mappi-I board was the first platform, which had been used | |
73 | to port and develop a Linux system for the M32R processor. | |
74 | Currently, the Mappi-II, an heir to the Mappi-I, is available. | |
