TCM alternative in A15

Note: This was originally posted on 19th October 2012 at http://forums.arm.com

Hi

We want to use an A15 core for some packet processing function with a really high throughput. This means that every packet is going to cause a cache miss if we use the regular caching mechanism.
In order to avoid that, we could two things

1. Use TCMs. But these are not present in the Cortex A series. Does anyone know an alternative to this that A15 supports?
2. Stash the data directly into the L1 cache. But I could not find any information whether this is possible.

Can any one suggest what would be the best way to achieve this high throughput packet processing using A15?

Thanks

I'm pretty sure that A15 does speculative access.
