Arm MultiTrace Overview

• MultiTrace passively collects information from an ARM based SoC containing an Embedded Trace Macrocell (ETM). The ETM monitors the ARM instruction and data buses at full core speeds.
• It collects trace information at clock speeds of up to 200MHz.
• Uploading to Trace Debug Tools (TDT) uses Ethernet 10/100baseT
• Data port widths of 4, 8, and 16 bits are supported.
• A half rate trace clock is supported that captures data on both the rising and falling clock edges.
• The SoC voltage can be in the range of 1.0 to 3.3V.
• Trace information is time stamped at a resolution of 10ns.
• MultiTrace forms one component in the ARM Real-Time Trace (RealTrace) debugging system. RealTrace consists of:
  • Trace Debug Tools (TDT)
  • MultiTrace
  • Multi-ICE
  • RealMonitor.
