The test did finally finish and here is the output of tsim's perf command: *** END OF TEST WHETSTONE *** Program exited normally. tsim> perf Cycles : 74462444473 Instructions : 45632185502 Overall CPI : 1.63 CPU performance (50.0 MHz) : 30.64 MOPS (30.64 MIPS, 0.00 MFLOPS) Cache hit rate : 98.0 % (inst: 97.9, data:99.7) AHB bandwidth utilisation : 34.8 % (inst: 14.1, data: 20.8) Simulated time : 1489.25 s Processor utilisation : 100.00 % Real-time performance : 122.02 % Simulator performance : 37.39 MIPS Used time (sys + user) : 1220.46 s So it just took a LONG time. --joel > -- > Sebastian Huber, embedded brains GmbH > > Address : Dornierstr. 4, D-82178 Puchheim, Germany > Phone : +49 89 189 47 41-16 > Fax : +49 89 189 47 41-09 > E-Mail : sebastian.hu...@embedded-brains.de > PGP : Public key available on request. > > Diese Nachricht ist keine geschäftliche Mitteilung im Sinne des EHUG. > >
