2 System Board
Chip-Set
Chip-Set
The chip-set comprises two chips. These interface between the three main
buses (the Processor-Local bus, the PCI bus and the ISA bus).
• The Bridge chip (SiS5581) is a combined PL/PCI bridge and cache
controller and main memory controller and PCI/ISA bridge and IDE
controller and USB controller.
• The Super I/O chip (NS87317) is a combined serial interface and paral-
lel interface and keyboard controller and mouse controller and flexible
disk drive controller.
PL Bus Interface
PCI Bus Interface
Bridge Chip (SiS5581)
The bridges between the Processor Local Bus (PL Bus) and the PCI Bus,
and between the PCI Bus and the ISA Bus, are encapsulated in a 553-pin ball
grid array (BGA) package.
The chip monitors each cycle that is initiated by the processor, and forwards
those to the PCI bus that are not targeted at the local memory. It translates
PL bus cycles into PCI bus cycles.
The chip supports the SMM mode of the Pentium processor, the CPU stop
clock hardware function, and the keyboard lock function.
The chip-set is PCI 2.1 compliant, and provides for PCI Concurrency.
Concurrent data transfers that do not contest for the same resources (such
as processor to memory concurrent with PCI peer to peer, or processor to
ISA device concurrent with PCI device to memory) are allowed to interleave
their transfers.
The PCI arbiter supports PCI bus arbitration for up to four masters using a
rotating priority mechanism. Its hidden arbitration scheme minimizes
arbitration overhead.
ISA Bus Interface
As well as accepting cycles from the PCI bus interface, and translating them
for the ISA bus, the ISA bus interface also requests the PCI master bridge to
generate PCI cycles on behalf of a DMA or ISA master. The ISA bus interface
contains a standard ISA bus controller and data buffering logic, and can
18
support up to three ISA slots without any external buffering.
2 System Board
Chip-Set
Data Path
Level-2 Cache Memory
Controller
Storage elements are provided for bidirectional data buffering among the
64-bit PL data bus, the 64-bit memory data bus, and the 32-bit PCI address/
data bus. This buffering is used, partly, to smooth the differences in
bandwidths between the three buses, thereby improving the overall system
performance.
The Level-2 cache memory controller supports write back direct mapped
pipelined burst static RAM. On the HP Vectra VE 5/xxx Series 4 PC, 256KB
of write back cache memory is implemented as two 32K ✕ 32-bit chips
soldered on the system board. The 8-bit tag allows the lowermost 64 MB of
main memory to be cached (if more than 64 MB of main memory is installed,
accesses to the uppermost regions will be made directly to the main memory
modules, and not via the cache memory mechanism).
The cache memory line width is 32-bytes (256-bits), four times the width of
the Processor-Local data bus. Reads and writes always involve a full cache
line, and so require four back-to-back cycles on the bus. Since they involve
accesses to related addresses, they do not need four independent accesses
to main memory, but can be organized as a pipelined burst. The second,
third and fourth cycles in each burst require less time to complete than the
first, the first cycle having included the addressing phase and memory precharge timing. The read and write access timing has the pattern 3-1-1-1.
However, the timing for 64-byte burst reads can be even better than this (31-1-1,1-1-1-1 for a back-to-back burst read) provided that the main memory
banks have been filled contiguously.
Main Memory Controller
There are two programmable non-cacheable regions, with an option to
disable local memory in these regions. A 64 KB to 1 MB cache summary is
provided.
The main memory controller supports up to 384 MB of EDO, FPM or
SDRAM double interline memory modules (DIMMs). The HP Vectra VE 5/
xxx Series 4 PC supports three modules of SDRAM (synchronous dynamic
random access memory). With the 64 MB module from HP, this gives a
maximum total capacity of 192 MB.
In the case of 66 MHz PL bus operation, memory accesses have a timing
pattern of 6-1-1-1 for a page-hit. This degrades to 10-1-1-1 for a page-miss.

2 System Board
Chip-Set
IDE Controller
USB Controller
DMA Controller
Interrupt Controller
The PCI master/slave IDE controller, supporting four devices, two on each of
two channels, is described on page 26. As well as the traditional five PIO
modes (0 to 4) and three DMA modes (0 to 2), this controller also supports
three Ultra ATA/33, or Ultra DMA, modes (0 to 2), allowing peak transfer
rates up to 33 MB per second.
The PCI USB controller, supporting two connectors, is described on page 28.
The seven channel DMA controller incorporates the functionality of two
82C37 DMA controllers. Channels 0 to 3 are for 8-bit DMA devices, while
channels 5 to 7 are for 16-bit devices (as described on page 60). The
channels can be programmed for any of the four transfer modes: the three
active modes (single, demand, block), can perform three different types of
transfer: read, write and verify. The address generation circuitry can only
support a 24-bit address for DMA devices.
The sixteen channel interrupt controller incorporates the functionality of
two 82C59 interrupt controllers. The two controllers are cascaded, giving 14
external and two internal interrupt sources (as described on page 61).
Counter / Timer
The chip contains a three-channel 82C54 counter/timer. The counters use a
division of the 14.318 MHz OSC input as the clock source.
Super I/O Chip (
The Super I/O chip is contained within a 160-pin PQFP package. It includes
the following features:
• ACPI register set
• Five Power-On/SCI/SMI channels
• Two SMI channels
• Signal line to an external light
• Power-State bit for PIIX4-based designs.
The chip provides the control for the following devices.

The 9-pin serial port (whose pin layout is depicted on page 46) supports RS232-C and is buffered by a 16550 UART, with a 16 Byte FIFO. It can be
programmed as COM1, COM2, COM3, COM4, or disabled.
The 25-pin parallel port (also depicted on page 46) is Centronics
compatible, supporting IEEE 1284. It can be programmed as LPT1, LPT2, or
disabled. It can operate the four modes:
Standard mode (PC/XT, PC/AT, and PS/2 compatible).
❒
Bidirectional mode (PC/XT, PC/AT, and PS/2 compatible).
❒
Enhanced mode (enhanced parallel port, EPP, compatible).
❒
High speed mode (MS/HP extended capabilities port, ECP, compatible).
❒
The integrated flexible drive controller (FDC) supports any combination
of two from the following: tape drives, 3.5-inch flexible disk drives, 5.25-inch
flexible disk drives. It is software and register compatible with the 82077AA,
and 100% IBM compatible.
The computer has an 8042-based keyboard and mouse controller. The
connector pin layouts are shown on page 46. The Power-on keyboard is
described on page 29.
RTC
The real-time clock (RTC) is 146818A-compatible. With an accuracy of
20 ppm (parts per million). The configuration RAM is implemented as 256
bytes of CMOS memory.
