The ARM implementation of the JTAG standard for this task replaces the TDI and TDO pins with the single bidirectional pin SWDIO. The Morris worm exploited a command injection in a Unix sendmail mode intended for this purpose. This task can be performed using the netlist insertion method, in which an integrated logic analyzer traces the post-synthesis netlist. The x command in one tool for this task (-5[1])executes PEEKTEXT and POKETEXT using the Unix system call (*) ptrace. IBM Purity is often used to perform this task for memory occurrences, while gdb and lldb (10[2])are more general tools for performing this task. This task can be primitively performed on hardware by inserting breakpoints between instructions or by single-stepping. (10[1])For 10 points, name this process of removing errors from code. ■END■ (10[2])
