I\'m optimizing a Linux boot on PowerPC MPC83xx. I\'m trying to optimize the kernel image copy, from nand to ram and trying to check or change the write policy of the cache.
I have to approximate execution time of PowerPC and x86 assembler code.I understand that I cannot compute exact it dependson many problems (current processor state - x86 processor dicides internal ins
my elf-file is about 1MByte with all debug symbols. As I try to create a binary file with \"powerpc-eabi-objcopy -O binary out.elf out.bin\" the out.bin is 1GByte huge.
Is there a conditional-move-equivalent on the Po开发者_JAVA百科werPC (32 or 64) instruction set?It can obviously be emulated using a conditional branch, but I want something that outperforms that.Powe
