PA-7100

The PA-7100 is a microprocessor developed by Hewlett-Packard (HP) that implemented the PA-RISC 1.1 instruction set architecture (ISA).It was introduced in early 1992 and was the first PA-RISC microprocessor to integrate the floating-point unit (FPU) on-die.It operated at 33 – 100 MHz and competed primarily with the Digital Equipment Corporation (DEC) Alpha 21064 in the workstation and server markets.Samsung also introduced workstations running HP-UX based on the PA-7100 and system technology licensed from HP.[1] It was based on the PA-7000 (PCX-S) chip set, a previous PA-RISC implementation consisting of a microprocessor and FPU.
