The Primitives Library Introduction The purpose of the primitives library is to give the freerdp code easy access to run time optimization via SIMD operations When the library is dynamic checks of processor features are	run (such as the support of SSE3 or Neon)

The Primitives Library Introduction The purpose of the primitives library is to give the freerdp code easy access to run time optimization via SIMD operations When the library is dynamic checks of processor features are and entrypoints are linked to through function pointers to provide the fastest possible operations All routines offer generic C alternatives as fallbacks Run time optimization has the advantage of allowing a single executable to run fast on multiple platforms with different SIMD capabilities Use In Code A singleton pointing to a structure containing the function pointers is accessed through	primitives_get (). The function pointers can then be used from that structure

Of there is some overhead in calling through the function pointer and setting up the SIMD	operations

Of there is some overhead in calling through the function pointer and setting up the SIMD so it would be counterproductive to call the primitives library for very small	operation
