术语 | double bus fault |
释义 | double bus fault 双总线故障;[双汇流排故障] The problem happened when two bus errors occur in a row. When a bus error exception occurs, the processor will attempt to stack several words containing information about the state of the machine. If a bus error exception occurs during the stacking operation (before the execution of the next instruction), there will have been two bus errors in a row,or what is commonly referred to as a double bus fault. When a double bus fault occurs, the processor will halt. 当连续出现两个总线错误时所产生的问题。当一个总线出现错误时,处理机将设法把几 个含有该机器状态信息的字送进栈内。如果在进栈操作期间(执行下一指令之前)又有一总 线错误出现,这就有了连续的两个总线错误,即通常所指的双总线故障。双总线故障发生时, 处理机将停机。 |
