What is the difference between a PA-8500 and a PA-8200?
The PA-8500 has a 512 KB instruction cache and a 1 MB data cache. Other improvements to the microarchitecture include a larger BHT containing 2,048 entries, twice the capacity of the PA-8200's, and a larger TLB containing 160 entries. The PA-8500 uses a new version of the Runway bus.

Precision Architecture RISC (PA-RISC) or Hewlett Packard Precision Architecture (HP/PA or simply HPPA), is a general purpose computer instruction set architecture (ISA) developed by Hewlett-Packard from the 1980s until the 2000s.
The architecture was introduced on 26 February 1986, when the HP 3000 Series 930

People also ask
When did the HP PA-8500 come out?
Introduced in September 1998, the PA-8500 marked a break with the long-standing HP tradition of keeping large L1 caches off-chip. (The two years older PA-7300LC also included on-chip L1 caches, albeit much smaller). There were no other significant changes to the processing core, besides small increases to the TLB and BHT.

Who made the HP PA-8500 microprocessor?
It was fabricated by Intel Corporation in a 0.25 μm CMOS process with five levels of aluminium interconnect. It uses a 2.0 V power supply. HP did not fabricate the PA-8500 themselves as they had ceased to upgrade their fabs to implement a process newer than CMOS-14C, which was used to fabricate previous PA-RISC microprocessors.

How much bandwidth does a PA-8500 use?
The PA-8500 uses a new version of the Runway bus. The new version operates at 125 MHz and transfers data on both rising and falling edges of the clock signal (double data rate, or DDR) and yields 240 MT/s or 2 GB/s of bandwidth. As the Runway bus is used to transfer addresses and data, usable bandwidth is 80% that of 2 GB/s, or around 1.6 GB/s.
