What kind of bursts will the ARM966E-S perform?

Applies to: ARM966E-S


The ARM966E-S processor will use SINGLE/INCR4/8/16 bursts to transfer multiple register-data when executing LDM and STM instructions. For example, a LDM of 10 registers will be split up into an INCR8 burst and 2 SINGLE transfers. Similarly, a STM of 5 registers will be split up as an INCR4 burst plus 1 SINGLE.

A LDM/STM of all 16 registers should be executed as an INCR16 burst. Only word-wide transfers are supported with fixed-length incrementing
