ARM7 Programming question!

Velagala J R N D V Reddy

Hi

I had a doubt about programming the arm7. In which scenario I should use explicitly Assembly language instructions while programming.

Thanks

    We could add a few more examples to that list...

    • Access to machine registers like the CPSR
    • To use native machine instructions, like SIMD arithmetic, which do not map onto C syntax/semantics
    • In relatively rare cases, to achieve higher performance than the compiler can achieve

    Hope this helps
