The ARM implementation of the JTAG standard for this task replaces the TDI and TDO pins with the single bidirectional (-5[1])pin (15[1])SWDIO. The Morris worm exploited a command injection in a Unix sendmail mode intended for this purpose. (15[1]-5[1])This task can be performed using the netlist insertion method, in which an integrated logic analyzer traces the post-synthesis netlist. The x (15[1])command in one tool for this task (-5[1])executes PEEKTEXT and POKETEXT using the Unix system call (*) ptrace. (10[1])IBM Purity is often used to perform this task for memory occurrences, while gdb (10[1])and (10[2])lldb (10[6])are more (10[2])general (10[2])tools (10[1]-5[1])for performing (10[1])this task. (10[1])This task can be primitively performed on hardware by inserting breakpoints (10[2])between instructions (10[3]-5[1])or by (10[2]-5[1])single-stepping. (10[6])For 10 points, (10[2])name this (10[1])process of removing errors from code. (10[3])■END■ (10[8])
