Hi I have built SID and a cross toolchain of arm-elf, then I ran SID with a toy program. But I can not get any information of the hardware--I mean something like cycle, time or instruction counts, just as what gdb-sim provides. I read the mannual, and found that there is no option about the hardware performance. However, maybe it is because that I don't know any one is the one. Where is the hardware performance information? Thank you for your help! Dam Wang _________________________________________________________________ ÏíÓÃÊÀ½çÉÏ×î´óµÄµç×ÓÓʼþϵͳ¡ª MSN Hotmail¡£ http://www.hotmail.com
