Monitorable events
Monitorable events
Event monitored and counted
Instruction cache miss. Incremented once for each instruction fetch from a cacheable memory area that did
not hit in the cache.
Instruction fetch stage stall. Incremented every cycle the memory system is unable to deliver an instruction
to the CPU.
Data hazard stall. Incremented every cycle the condition is true.
ITLB miss.
DTLB miss.
Branch instruction executed. May or may not be taken.
Branch mispredicted.
Instruction executed. Incremented once each time an instruction is completed.
Stall due to data cache write buffers full. Incremented once for each occurrence.
Stall due to data cache write buffers full. Incremented every cycle the condition is true.
Stall due to data cache read miss. Incremented once for each data access to a cacheable memory area
that did not hit in the cache.
Stall due to data cache read miss. Incremented every cycle the pipeline is stalled due to a data access to a
cacheable memory area that did not hit in the cache.
Write access counter. Incremented once for each write access.
Write access counter. Incremented every cycle a write access is ongoing.
Read access counter. Incremented once for each read access.
Read access counter. Incremented every cycle a read access is ongoing.
Cache stall counter. Incremented once for each read or write access that stalls.
Cache stall counter. Incremented every cycle a read or write access stalls. Write accesses are counted
only until the write is put in the write buffer.
Cache access counter. Incremented once for each read or write access.
Cache access counter. Incremented every cycle a read or write access is ongoing. Write accesses are
counted only until the write is put in the write buffer.
Data cache line writeback. Incremented once when a line containing dirty data is replaced in the cache.
Accumulator cache hit
Accumulator cache miss
BTB hit. Incremented once per hit occurrence.
Micro-ITLB miss. Incremented once per miss occurrence.
Micro-DTLB miss. Incremented once per miss occurrence.
Reserved.
The following events can be monitored by the performance counters, depending on the setting
of CONF0 and CONF1, see
