wrong cycle timing of instructions on ARM11

Note: This was originally posted on 4th February 2013 at http://forums.arm.com

Hi,

Iam using RVDS3.0 for ARM11. some of the instructions are not executing in the time specified by the ARM documentation. for example, according to ARM documents, SMLAD instruction has to take 1 cycle for execution and 2 stalls if the result is immediatly used. but in real time, it is taking 2 cycles for execution. is it a bug on RVDS3.0 or am i missing any thing here. can any one please help me out.

Regards,
Chandrakala
