But by the third and fourth versions, with the customer requesting added functionality all the time, we were banging hard on the …
This course is all about tuning your code. It’s about how you can improve your C specifically for ARM CPUs so that it runs faster, takes up less space or possibly both. After groundwork, the first half covers basic optimisations. Theoretically most of these improvements should apply to the majority of CPUs.
4/5/2006 · Many architectures, such asthe ARM, and PowerPC, are more efficient at loading unsigned charactersthan they are at loading signed characters. Other architectures, suchas the V800 and SH, handle signed characters more efficiently. Mostarchitectures’ ABIs define the plain “char” type as whichever type ismost efficient.
Writing Efficient C and C Code Optimization – CodeProject, Writing Efficient C and C Code Optimization – CodeProject, Efficient-C-for-ARM . Examples from my Efficient C for ARM training course, Then the Efficient C for ARM page goes on to inspect some examples, take your C++ code and compile it, then disassemble, and see what is really happening. The problem with doing that is that you have to realize that there are many tuning knobs on a compiler and compilers are constantly evolving, and different compilers say, gcc, llvm (clang) and visual C/C++ are completely different.
