Higher Priority task deleting a lower priority task?

I have two tasks. task 1: searches for a string in a list of strings (n-strings are stored in the list). task1 priority: low task 2: invoked by uart receive interrupt to abort the search. task 2...

Higher Priority on UART1

How can I increase the interrupt priority of UART1 of the LPC2364? Due to heavy load on timer interrupts, I'm missing receiving characters every 5 - 10 seconds. The initialization of UART1 is as...

Why the overhead of memcpy() in EL3 is higher than in NS.EL1?

I evaluated the performance overhead of memcpy (memory copy) in both NS.EL1 (kernel module) and EL3 (arm trusted firmware): 1. I allocated two contiguous physical memory buffers A and B via Linux...
