Hi ,
Am currently porting my linux c++ project into ARM - linux processor.
Timing of my linux project was 1ms in Linux (kernel:3.13.0-32-generic) and timing for the same in ARM linux is 15ms !!
I understand that due to MIPS difference the executio time differs :
ARM cortex A8 : 2000 MIPS at 1.0GHz (Dedicated processor)
Intel i5 : 83,000 MIPS at 3.3Ghz
My questions are :
1) how to utilize the available 256KB L2 cache efficiently ?
2) A memorymap file similar to DSP is available for ARM ? How MSMCSRAM and DDR3 access is done in code ?
I could not find any example program for the same ?
ARM cortex Linux kernel : kernel:3.4.40-armv7l
compiler : arm-linux-gnueabihf-g++-4.8
Thank you
