HP 9000/500 FOCUS 4.56 HP 9000/500 FOCUS (With Frank McConnell; some parts taken with permission from him) 4.56.1 Overview The HP 9000/500s computers were the early-1980s predecessors of the PA-RISC workstations and the first member of the HP 9000 series. Although already based on a HP 32-bit processor — the FOCUS — they did not have PA-RISC CPUs. The HP 9000/520 (originally 9020, the first 500 series) was introduced in 1982 by HP and one year later described in the Hewlett Packard Journal as “[. . . ] the new HP 9000 computer, a mainframe on the desktop [. . . ].” All 500s used the same processors, memory and I/O; differences were in expandability and built-in I/O. The HP 9000/500 series was withdrawn after several years (production stopped in 1989), probably due to the complexity and cost of its architecture (the five years younger first PA-RISC NMOS implementation had one third the FETs of the FOCUS processor). 4.56.2 Processors The basic architecture of the 500 series was based on the Hewlett-Packard FOCUS architecture, implemented in five NMOS-III VLSI ICs (fabbed in 1.5 micron): the CPU chip, I/O processor (IOP), memory controller, 128Kb RAM (16 KB cache) and clock driver. The CPU ran at 18 MHz and had a “direct address range” of “500 MB” (probably 29-bit direct addressing for 512 MB). It was fabricated with 450,000 FETs (integrated with three Floating-Point chips onto one “finstrate” CPU board). The FOCUS CPU was microcoded (9,000 38-bit microcode control stores) and implemented the HP 3000 computers’ stack-based architecture in 32-bit. All internal data paths and registers are 32-bit wide. Due to heat dissipation difficulties the ICs were mounted on special printed-circuit boards called “finstrates” — the board has a 1mm copper sheet as core to which the IC substrate is epoxied directly. The I/O Processor (IOP) executes all I/O instructions and handles the transactions from/to the eight attached HP CIO channels. It has an I/O bandwith of 5.1 MB/s (burst) and 973 KB/s (multiplexed). The IOP was also a microprogrammed (4,608 32-bit microcode stores) NMOS-III VLSI chip. At least one IOP to interface with the I/O buses was needed so up to six CPUs were supported in hardware (but only three in software). Up to two additional IOPs could be installed for more I/O options; each additional IOP needed an I/O expander which provided the I/O channels extension (CIO bus). The three finstrates boards (CPU, IOP and 256 KB RAM) were installed in a 12-slot (HP 9000/520) module. This allowed configurations of up to 10 MB of RAM; memory cards could be substituted to construct multiprocessor systems. The CPU, IOP and memory controller communicated via the memory processor bus (MPB). The 44-line, 18 MHz, 36 MB/s MPB supports up to seven (other sources mention three/three) CPUs or IOPs and fifteen memory controllers. 4.56.3 Systems Four distinct models were introduced between 1982 and 1984 (all based on the same architecture): 362
