术语 | software trace mode |
释义 | software trace mode 软件跟踪方式;[软体跟踪模态] A mode where the program stops and the internal status of the microprocessor is made available to the outside world wherever breakpoint conditions are met. In addition to the mnemonic instructions and the memory addresses, the user views register contents, program counter location, stack pointer and condition codes or flags. Breakpoints can be set at each instruction if so desired. The major advantage of this mode is the depth of insight it gives into program operation; it is fully interactive, enabling the user to alter register contents, make source code changes to correct program error, reassemble programs, and rerun to test corrections. 在满足断点条件时,程序停止运行并向外界提供微处理机内部状态的一种工作方式。除助记指令和存储器地址外,用户还可查看寄存器内容、程序计数器位置、栈 指示器以及条件代码或标志。如果需要,可以在每条指令上设置断点。这种工作方式 的主要优点是可对程序运行进行深入的了解,它完全是交互式的,能使用户改变寄存器内容, 修改源代码,以改正程序错误,重新汇编程序并重新运行以测试校正情况。 |
