Abstract
A method of debugging code that executes in a multithreaded processor having microengines includes receiving a journal write command and an identification representing a selected one of the microengines from a remote user interface connected to the processor, pausing program execution in the threads executing in the selected microengine, inserting a journal write command at a current program counter in the selected microengine, resuming program execution in the selected microengine, executing a write to a journal routine if program execution in the selected microengine encounters the journal write command and resuming program execution in the microengine.
