Method and system for improved communication between central processing units and input/output processors

摘要

A method and system for communicating information regarding input/output (IO) processing in a shared access to memory environment is disclosed. A central processing unit (CPU) and an input/output processor (IOP) are configured to write to and read from predetermined memory locations to manage the detection, performance, and completion of IOs. The CPU and the IOP may read from and write to memory as desired.
