Abstract for z/XC Principles of Operation
IBM® z/Architecture® Extended Configuration (z/XC) virtual-machine architecture, as provided by z/VM®, is described in detail. z/XC virtual machine operation is described as it appears to an assembly language programmer. Because z/XC is based on and is closely related to z/Architecture, z/XC is defined by indicating the ways in which it is the same as, or different from, z/Architecture.
The following elements of the z/XC architecture are covered:
- Overall organization
- The structure of storage and address spaces
- Control facilities
- Program execution
- Interruptions
- The operation of instructions
- Input/output facilities
