# 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.
|
|
|
|
|
|
* gen-configurable
|
|
|
|
* nia width, number of buckets, ...
|
|
* local bram size
|
|
|
|
* csr-configurable
|
|
|
|
* buckets def
|
|
* ctls (start/stop/rst/...)
|
|
|
|
* wb interface to connect to uart/eth/mem
