硬件瞬时故障可以通过修改指令操作码和操作数的方式引发控制流错误,破坏程序的正常执行。
Hardware transient faults can cause control flow errors and corrupt the normal execution process by altering the operand and opcode of instructions.
调试这个问题的一种方法是对这个可执行程序执行objdump命令,并将其结果保存到一个文件中;然后查找出错的指令(在本例中,出错的操作码是98080000)。
One way of debugging this failure is to do an object dump of the executable and save it in a file, then search for the failed instruction (in this case, the failed opcode is 98080000).
控制电路翻译操作码,并且通过发送相应的控制信号来执行指令。这些信号控制数据的传送和ALU操作的执行。
Control circuitry interprets the opcode and executes the instruction by sending out the appropriate control signals to cause data to be moved or an operation to be performed by the ALU.
该系统的用户可通过程序控制处理过程,所谓程序是指定操作、操作码及执行处理序列的指令集合。
The data processing task may be altered simply by specifying a new program with different instructions or specifying the same instructions with different data.
