Cortex A9 Preload Engine is not implemented in iMX6?

Hello,

In i.MX 6Dual/6Quad Applications Processor Reference Manual (imx6dqrm.pdf )

I see the following -

12.3.2 Core configuration

Table 12-4. Cortex-A9 Core configuration

PRELOAD_ENGINE_PRESENT - No

Does that mean that no automatic cache preload functionality is available on imx6?

Does that mean that PLD assembly instruction could not be used to optimize memory reads?

Thanks.

Hi,

According to the RM, the Cortex lacks of the Preload Engine.

Thanks!

Does that mean that I can't use PLD assembler command to pull the data I need for calculations into L2 ?

Hi,

Sorry for the delay,

It seems that you may use them but I suggest you to take a look at the errata first:
