Hi all,
recently I did some measurements concerning the SysTick-Timer and consumend clock cycles (because of performance reasons).
I wrote a simple function in assembly, which gets called from a C file. Before and after the call i read the value of the SysTick-Timer to determine the cycles neeed for loading the parameter value into register r0, the call and all the assembly code in the function.
Taking into account, that two consecutive (simple) LDR instructions can get pipeplined, it seems they don't get pipelined - at least when looking at the clock cycles.
Am I right assuming that loads to different memory regions (for SysTick-Timer and stack) don't get (ever) pipelined ? And maybe a slightly other question: do loads get pipelined when crossing boundaries concerning "minimum memory part sizes" (AHB-Lite) in the same memory region?
Thanks in advance,
Alex
