About: Enforce In-order Execution of I/O

An Entity of Type: programming language, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Enforce In-order Execution of I/O (EIEIO) is an assembly language instruction used on the PowerPC central processing unit (CPU) which prevents one memory or input/output (I/O) operation from starting until the previous memory or I/O operation completed. This instruction is needed as I/O controllers on the system bus require that accesses follow a particular order, while the CPU reorders accesses to optimize memory bandwidth usage.
