PA-RISC Processors

PA-8200 (PCX-U+)

Overview

The PA-8200 is a 64-bit PA-RISC processor from HP, that extended the original 64-bit PA-8000 soon after its released. Several aspects of the PA-8000 should be improved in the PA-8200, which was released in 1997: branch prediction, TLB miss rates and cache sizes.

The PA-8200 should offer improved performace, compatibility with existing applications and short time to market. The availability of new 4 Mb SRAMs with faster access times allowed for increased CPU speed and larger caches. Smaller changes include an increase to the BHT and TLB as high benefit, low risk improvements.
