PA-RISC Processors



The PA-8900 is a slightly tweaked PA-8800 processor with a doubled L2 cache and higher clock frequency, released in 2005 only one year after the PA-8800. It is probably the last processor of the PA-RISC family, with all future systems will being based on Itanium-family chips. After HP dropped its line of Itanium workstations the PA-8900-powered C8000 were one of the last HP-UX workstations.

Information on the PA-8900 is limited, with apparently not much interest in releasing details on its architecture.
