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.
