Local Bus Devices

• Intel Pentium Pro (P6) microprocessor
• optional second Pentium Pro processor (HP Vectra XU 6/xxx PC only)
• main memory controller and its memory modules
• error correcting code (ECC).
The Pentium Pro is a super-pipelined, dynamic branch-prediction,
asynchronous super-scalar Intel microprocessor. Within the single integrated
circuit package Intel provide a Level-Two (L2) cache memory chip and the
microprocessor. The former contains 256 KB of synchronous cache memory;
the latter includes two Level-One (L1) cache memories (an 8 KB instruction-
code cache memory, and an 8 KB data cache memory).
Software written for previous HP Vectra PCs will run on the Pentium Pro.
However, only 32-bit programs execute faster. The Pentium Pro is not pin
compatible with the Pentium.
The HP Vectra XU 6/xxx PC has a socket for installing a second Pentium Pro
processor. However, to do so is only an advantage when running an operating
system that supports multiprocessing ("MPS-ready"), such as SCO-Unix,
NextStep, Solaris, OS/2 SMP and Windows NT. Of these, the Windows NT
operating system makes best use of the Pentium Pro's 32-bit architecture
(though other operating systems will also show some benefit if 32-bit
application programs are run).
