摘要：An input/output processor architecture for providing an interface betweenperipheral subsystems and a generalized data processor. The interface processorenables data to be transferred between two address spaces (the generalized dataprocessor address space and an external processor I/O address space) by mapping aportion of the I/O address space into a portion of the GDP address space. This mappingfacility provides the peripheral subsystem with a \"window\" into the associated GDPsubsystem. It accepts addresses within a certain subrange, or subranges, and translatesthem into references into one or more GDP data segments.
A function-request facility provides a functional capability over certain objects withinthe GDP address space.
< P>The two facilities provide software on an external processor with a window intothe address space of the GDP that enables the software, via the function request means,to send messages to and receive messages from the GDP and to manipulate anenvironment provided for the external processor within its address space.
