HP 3AA1-1106 CPU in codice Landshark, era inserito nei sistemi RISC PA-8600 che era un sistema tipo PA-8500 con alcune modifiche atte a sopportare una frequenza più elevata. Altra modifica riguardava la cache.

Il sistema PA-8600 versione 2.0 era a 64 bit e aveva le seguennti caratteristiche.

• 10 functional units : 2 integer ALU, 2 shift/merge units, 2 complete load/store pipeline, 2 Floating-point multiply/accumulate units, 2 Floating Point divide/square roots units
• 4-way superscalar
• 2 address adders
• 160 entry fully-associative dual-ported TLB
• 32 entry BTAC
• 2048 entry BHT
• dynamic and static branch prediction modes
• on-chip L1 caches 0.51MB I and 1 MB D, each 4-way set associative
• 32 or 64 Byte cache line size
• Supports up to 1TB of physically addressable memory
• 56 entry instruction queue/reorder buffer
• MAX-2 multimedia extensions for multimedia applications, e.g. MPEG decoding
• Quasi LRU replacement policy for the instruction cache
• bi-endian support
• Runway system/memory bus, 125 MHz, 64 bit, DDR, about 2GB/s peak bandwith
• Up to about 550 MHz frequency with 2.0v core voltage

Veniva usato in :

• A400-5X
• B2000, B2600
• C3600
