e200z0 (MPC560xB) Divider Logic Performance

Hello Community,

 

the MPC560xB reference manual describes the e200 integer unit's features like that:

• Divider logic for signed and unsigned divide in 5 to 34 clocks with minimized execution timing

• 8x32 hardware multiplier array supports 1 to 4 cycle 32x32->32 multiply

 

The e200z0 reference manual says the timing is "data dependent".

 

Is there a document (I didn't see yet) giving more information (e.g. a table with the different div and mul instructions with timings)?

 

 

Best Regards,

Martin
