-## Motivation
+# Motivation
 
 Power ISA currently has some issues with its atomic operations support,
 which are exacerbated by 3D Data structure processing in 3D
 Shader Binaries needing
 of the order of 10^5 or greater atomic locks per second per SMP Core.

 Having single atomic operations is useful for implementations that want to send atomic operations to a shared cache since they can be more efficient to execute there, rather than having to move a whole cache block. Relying exclusively on
