A Primer: ARM Trace - SASE
a primer : ARM TraceIncluding:ETM , ETB and Serial Wire Viewer, JTAG and SWDV introduction How we talk to your CPU using JTAG or SWD. Trace . ETM , ETB and SWV. How are they different ? Triggers, filters and Instrumentation. DCC and ITM. Breakpoints and Watchpoints What is Trace good for ? Some Skill Set Trace : around for a long, long time. Not many use it maybe < 5%. The best do. Trace helps you find the nastiest And often fairly just like ..is good for testing software and hardware too. Developer productivity is very So let s look at the various technologies ARM Public Processor Roadmap4 Cortex M3 Cortex M1SC300 Cortex A8 Cortex A9 (MPCore )ARM7 ARM7 TDMI ARM11 (MPCore )ARM9 Cortex M02007 Cortex A5 Cortex M4 Cortex A15 Cortex A9 (Dual)Up to 2 GHz~600 to 1 GHz72 150 + MHzCortex R4 FCortex R4 Cortex R5 MicrocontrollerApplicationReal timeARM 7, 9, 11Up to GHzARM926EJ S Cortex M0 DesignStart Cortex R7 Cortex A7200+ MHz200+ MHz50 MHzV8 (64 BiAll dates are EmbeddedICECoreSight Not to scaleCortex A5 Cortex M0+Cortex A5 Cortex A12 ARM Public Processor Roadmap5 Cortex M3 Cortex M1SC300 Cortex A8 Cortex A9 (MPCore)ARM7 ARM7 TDMIARM11(MPCore)ARM9 Cortex M0 Cortex A5 Cortex M4 Cortex A15 Cortex A9 (Dual)Up to 2 GHz~600 to 1 GHz72 150 + MHzCortex R4 FCortex R4 Cortex R5 MicrocontrollerApplicationReal timeARM 7, 9, 11Up to GHzARM926EJ SCortex M0 DesignStartC)
