As with all assembly the key is to know and understand the algorithm. Know where the processor is spending most of it's time. Keep as much of your current state in registers, store remaining state in the stack frame (confined and cached). Avoid sparse accesses to main memory to avoid cache pollution. Elimate unnecessary loads and stores. Know the resources of the processor, register set and execution units.
