  Central Processor (CP): This processor type is available for normal operating system and application software.

  System Assistance Processor (SAP): Every modern mainframe has at least one SAP; larger systems may have several. The SAPs execute internal code to provide the I/O subsystem. An SAP, for example, translates device numbers and real addresses of channel path identifiers (CHPIDs), control unit addresses, and device numbers. It manages multiple paths to control units and performs error recovery for temporary errors. Operating systems and applications cannot detect SAPs, and SAPs do not use any "normal" memory.

  zIIP: The System z9® Integrated Information Processor (zIIP) is a specialized engine for processing eligible database workloads. The zIIP is designed to help lower software costs for select workloads on the mainframe, such as business intelligence (BI), enterprise resource planning (ERP) and customer relationship management (CRM). The zIIP reinforces the mainframe's role as the data hub of the enterprise by helping to make direct access to DB2® more cost effective and reducing the need for multiple copies of the data.
