Interleaved Architecture Tracing and Microarchitecture Tracing

摘要

Systems and method for embedded trace macrocell (ETM) devices configured to dynamically interleave architecture/program tracing with microarchitecture/hardware tracing. An ETM device includes logic to enable interleaved program tracing and hardware state sampling. A core interface is configured to receive program trace and hardware state information of a microprocessor and a combining module is configured to interleave the program trace and hardware state information. A packet generation module may be configured to packetize the program trace and hardware state information into packets at operational speeds of the microprocessor.
