编译方法

Makefile修改 在Makefile中取消LAB1 := -DLAB1_EX4 -D_SHOW_100_TICKS -D_SHOW_SERIAL_INPUT(第6行)的注释

LAB1    := -DLAB1_EX4 -D_SHOW_100_TICKS -D_SHOW_SERIAL_INPUT
# LAB2  := -DLAB2_EX1 -DLAB2_EX2 -DLAB2_EX3
# LAB3  := -DLAB3_EX1 -DLAB3_EX2
# LAB4  := -DLAB4_EX1 -DLAB4_EX2
# LAB5  := -DLAB5_EX1 -DLAB5_EX2
# LAB6  := -DLAB6_EX2
# LAB7  := -DLAB7_EX1 #-D_SHOW_PHI
# LAB8  := -DLAB8_EX1 -DLAB8_EX2
-D_SHOW_100_TICKS选项可在终端每是毫秒打印一行"100 ticks" -D_SHOW_SERIAL_INPUT选项会在终端打印键盘的输入 编译并运行代码的命令如下:
make

make qemu -j 16
补全代码后可以得到如下显示界面(仅供参考)
chenyu$ make qemu -j 16
