BMC.MODE Define the operating mode of the benchmark counter Format: BMC.MODE <mode> <mode>: OFF ICACHE DCACHE SYSIF CLOCK TIME This command only applies to some ARM9 based derivatives from Texas Instruments. The Benchmark Counter - short BMC - is a hardware counter. It collects information about the throughput of the target processor, like instruction or data cache misses. This information may be helpful in finding bottlenecks and tuning the application. OFF Switch off the benchmark counter. ICACHE Counts Instructions CACHE misses, in relation to total instruction access. DCACHE Counts Data CACHE misses, in relation to total data access. SYSIF Counts if SYStem bus InterFace is busy, in relation to total system bus access. CLOCK Incremented for each CPU clock. TIME TIME is measured by counting CLOCK. The translation to TIME is done by using the CPU frequency. For this reason, the CPU frequency has to be entered with the command BMC.CLOCK. ©1989-2014 Lauterbach GmbH ARM Debugger 124 ARM Specific Benchmarking Commands
