Hardware requirements
You should start with a minimal system with only,
- Nios II f or s core, with hardware multiplier, (f-core suggested, s-core is slower).
- sdram (minimum requirement 8MB),
- one full featured timer,
- a jtag/serial uart
Note in Linux, irq 0 means auto-detected, so you must not use irq 0 for ANY devices, except for timer.
It is possible to use e-core, but it will be very very slow.
It is possible to run without hardware multiplier, but you will need some hack.
硬件要求
你开始一个最小系统仅仅需要：
1、NIOS II f 或者s 处理器，带硬件乘法器（建议使用NIOS II /f,使用NIOS II/s很慢）
2、最小8M的SDRAM
3、一个全功能的定时器
4、JTAG/UART
备注：在Linux中，中断0意味着自动辨识，所以你不能把中断0分配给任何器件，除了定时器。没有硬件乘法器运行LINUX是可能的，但你需要一些hack。
