Thanks for providing such a convenient desktop software tool.

However, is there any document describing the metrics given by the analyzer? For instance:

- Instruction stats
- Main Body stats
- All Instructions:      308,     566 (rpt), ratio  1.84
- ALUs          :       41,      42 (rpt), ratio  1.02
- Half ALUs     :      126,     162 (rpt), ratio  1.29
- Total NOPs    :       41,     176 (rpt), ratio  4.29
- NOPs          :       30,     147 (rpt), ratio  4.90
- Post-NOPs     :       11,      29 (rpt), ratio  2.64
- MOV class     :       75,     150 (rpt), ratio  2.00
- MOVs        :       48,      76 (rpt), ratio  1.58
- FPConverts:        8,      32 (rpt), ratio  4.00
- Half MOVs   :       27,      74 (rpt), ratio  2.74
- CMP          :       15,      15 (rpt), ratio  1.00
- Texture Instrs:       14,      14 (rpt), ratio  1.00
- imm         :       14
- imm_a       :       14
- array       :        4
- isam        :       14
- Loads/Stores  :        8,      32 (rpt), ratio  4.00
- stib          :        8,      32 (rpt), ratio  4.00
- stibsize    :      128
- memory_stAllsize :      128
- EI Position   :       -1
- Flow Instrs   :       14
- BRAO Instrs   :        1
- Short sync flags:        8
- Long sync flags :        4
- Full Registers  :       16
- Half Registers  :       31
- uGPR Registers  :        4
- Unified Regs    :       16
- Total footprint :      256
- Single GPR Pool :        1
- Wave sizes      :       64
- Max num of waves:       12
- Maximal Waves   :        6 (A6x)

 

I don't think sombody can distinguish between "Max num of waves" and "Maximal Waves" if there's barely any documents.

If it is difficult to get a document can we have blog explaining the terms of the kernel analyzer.

Thanks
