MidTerm03

MidTerm Exam Problem 03:

请使用C语言，不使用库函数，直接使用MemoryWrite32()，MemoryRead32()对寄存器操作，实现《SOC微系统教程》实验四：中断-Timer_interrupt 的代码功能，为了节省时间，代码中PrintTimer()函数不需要实现。

Please use C without calling system functions (using MemoryWrite32(), MemoryRead32() directly to manipulate the registers) to implement the fourth experiment in the textbook (Timer_interrupt). The function PrintTimer() is not needed to be implemented.

MidTerm04

请使用C语言，不使用库函数，直接使用MemoryWrite32()，MemoryRead32()对寄存器操作，每0xffffffff个timer计数值输出一个字符，输出字符完成后，继续计数输出，最后输出字符串“ABC2020”。例如，timer每计0xffffffff个数，就通过uart0输出字符‘A’，输出完毕重新启动timer，计数到0xffffffff再次输出字符‘B’。请注意字符“2”与数字 2 的区别；timer计数值远小于0xffffffff，需要通过多次循环累加实现。

MidTerm05

使用C语言，可以使用库函数，每0xFF个timer计数值产生一次中断，在中断中输出一个字符‘A’，再重新启动计数器，退出中断。需要保证程序可以循环运行。例如，timer每计到0xFF，就产生一个中断，在中断中通过uart0输出字符‘A’，输出完毕重新启动timer，退出中断；计数到0xFF再次产生中断，在中断中通过uart0输出字符‘A’，输出完毕重新启动timer，退出中断，循环5次。
