Welcome to the ARM NEON optimization guide!
After reading the article ARM NEON programming quick reference, I believe you have a basic understanding of ARM NEON programming. But when applying ARM NEON to a real-world applications, there…
Hi,
I am working on bootloader porting to ARM v8 platform. I am facing a problem in enabling MMU in execution level-1 EL1.
I am not able to set sctlr_el1.M bit when ever i try to set this bit the instruction won't complete. I think it…

I'm not a native English speaker. So, sorry for the broken English. I'm intend to develop a system where the microcontroller will interface with a 8 bit parallel port IC. The bytes will be loaded into the microcontroller at the specific timing. As documented…
“At the end of the day, we must go forward with hope and not backward by fear and division.” – Jesse Jackson.
It often surprises me how many people believe that “ARM doesn’t do division” or “ARM cores don’t have…
Hi,
This question is for MMU and d-cache. When I tried to enable MMU and d-cache for u-boot I ran into Synchronous Abort handler while writing to PCIe device registers which I mapped as uncached memory. The dump is shown below
"Synchronous Abort" handler…
hi :
I know , we can flush L1 I/D cache items to PoU with kernel interface(flush_cache_*).
however, I can not find any clue about flushing L2 cache to DRAM(if without L3).
and I saw some points that L2 flushing was not needed.
for ARMv8, how can…
A programmable interrupt controller is an IP block that collates many sources of interrupt one one or more CPU lines, as well as submitting a level of priority to the interrupt outputs. It’s fair to say that almost every SoC needs an interrupt controller…
