Abstract:

Speed optimizations on pipelined/parallel hardware need
not be delegated to hardware mechanisms.  By removing
branches via software coding style, the programmer can
achieve speedup without relying on branch prediction schemes.
However, the branch removal comes at a cost.  Code is less
readable, maintainable, and testable.


Subject:	Code optimization for speed
