Abstract:
In accordance with embodiments disclosed herein, there is provided systems and methods for minimizing bandwidth to compress an output stream of an instruction tracing system. For example, the method may include identifying a current instruction in a trace of the IT module as a conditional branch (CB) instruction. The method includes executing one of generating a CB packet including a byte pattern with an indication of outcome of the CB instruction, or adding an indication of the outcome of the CB instruction to the byte pattern of an existing CB packet. The method includes generating a packet when a subsequent instruction in the trace is not the CB instruction. The packet is different from the CB packet. The method also includes adding the packet into a deferred queue when the packet is deferrable. The method further includes outputting the CB packet followed by the deferred packet into a packet log.
