NIAnalyzer
Programmable NIA analyzer and debugger
Receives debug bus (NIA, val, advancing, count, tag bits) and counts various events:
-
compare NIA vs all block specs (start/end) to match one or more blocks, or none (also counted)
-
count 'advancing' (count is for multiple completions)
-
could count 'valid and not advancing' cycles (latency); may only make sense for single ops
-
tag bits could specify b/alu/rot/ld/st/spec/etc. or other info (icmiss, dcmiss, stall, byps, ...)
-
could also be able to generate signal(s) based on events (stall/interrupt core when full), event seen, etc.
-
