AB527A is a two-core 1 GHz PA 8900 processor module for the HP 9000 rp4410. Its two cores share 64 MB of Level 2 cache, and each core has 1.5 MB of Level 1 cache, 3 MB per module. A floating point coprocessor is included.
The spare numbers for the module are AB527-69001, AB527-69002 and AD060-69001. All three are dual core CPU assemblies with a 1.0 GHz PA8900 CPU and 64 MB of L2 cache, and all three need PDC greater than 44.21.
The 1 GHz rp4410 base system is A9956A, with one active and one inactive 1 GHz core. AB525A activates the second core, and it has to be added before a second two core PA 8900 processor is installed. The rp4410 holds up to two PA-8900 processors (four cores). Two core modules can be installed one at a time, cores are filled in the sequence 0, 1, 2, 3, and 800 MHz and 1.0 GHz processors cannot be mixed in the same system.
Addressing on the processor is 44-bit physical and 64-bit virtual, with single bit cache error correction.
