Performance Estimation Categories Time and accuracy trade off among different performance estimations   0 0.2s 3~4 hrs 15~18hrs Func. TLM Exec. Time (MP3)‏ Accuracy 100% 99% ~92% ~80% Board Timed TLM ISM PCAM TLM: Transaction Level Model ISM: Instruction Set Model PCAM: Pin/Cycle Accurate Model
Proposed Design Methodology
Timed TLM Generation
Timed TLM
[object Object],[object Object],Experiment Results  (experiment setup)‏
Experiment Results ·  Error in TLM estimation is only  9%  compared to  19%  in ISM estimation ·  ISM cannot handle the design w/ custom HW components ·   Lines of code is  ~ 12K ·  Annotation time is  ~ 1 min ·  Perf. TLM can execute  ~ 0.2 sec ·  CAModel can execute  ~ 18 hour
