CHAPTER 1
Introduction
The ROBO-598 all-in-one single board computer is designed to fit a high
performance Pentium-based CPU and compatible for high-end computer system with
AGP and PCI Local Bus architecture. It is made to meet today’s demanding pace,
and keep complete compatibility with hardware and software designed for the IBM
PC/AT. It's beneficial to build up a high performance and high data availability
system for VARs, or system integrators. The on-board AGP (Accelerated Graphics
Port) graphics display will bring 3D performance to all segments of the PC market.
This single board computer can run with Intel Pentium or compatible processor up to
400 MHz, and support DIMM up to 768MB DRAM. The enhanced on-board PCI
IDE interface can support 4 drives up to PIO mode 5 timing and Ultra 33
synchronous DMA - Mode 2 transfer. The general Super I/O function by built-in
South Bridge Chipset integrates floppy controller, two serial ports, one FIR (Fast
Infra Red) port and one parallel port. Two high performance 16C550-compatible
UARTs provide 16-byte FIFOs, and the multi-mode parallel port supports
ECP/EPP/SPP function. Besides, two USB (Universal Serial Bus) ports provide
high-speed data communication between peripherals and PC.
The PICMG standard makes the ROBO-598 works with the legacy ISA, ISA/PCI or
pure multi-PCI backplanes. The on board 32-pin DIP socket supports M-system
Disk-On-Chip products up to 72MB. The Watch-Dog Timer function can monitor
your system status. Two 6-pin Mini-DIN connectors are provided to connect PS/2
Mouse and Keyboard. The on board Flash ROM is used to make the BIOS update
easier. A standard P8 power connector is reserved to directly get more power
energy for big power applications, and the additional 5-pin shrouded connector is
reserved for connecting Keyboard interface on the backplane. The high precision
Real Time Clock/calendar is built in for accurate scheduling and storing
configuration information. All these features make ROBO-598 excellent in stand-
alone applications.

1-3 System Architecture
In the following illustration, ROBO-598 gives a highly integrated system solution
and a most up-to-date system architecture, which includes two main VLSI chips
M1541/M1543C to support the Parity/ECC, PBSRAM, SDRAM, ACPI, Ultra-33
IDE Master, USB, PS/2 Keyboard/Mouse function, AGP graphics and Pentium-
compatible processors.
The North Bridge M1541 provides a complete integrated solution for the system
controller and data path components in a Pentium processor system. It provides a 64-
bit CPU bus interface, 32-bit PCI bus interface, 64/72 DRAM data bus with ECC or
parity to support three DIMMs, secondary cache interface, PCI master to DRAM
interface, and 4 PCI masters for external backplane support. In addition, it has a
built-in PCI-to-PCI bridge device to support the AGP interface (on board 3D VGA)
with 2X mode for high performance 3D graphics applications.
Specially, the M1541 integrates a high performance L2 write back/dynamic write
back direct mapping cache controller using MESI protocol of L1 and L2 to maintain
the data coherence for optimizing CPU bus utilization. The on-board L2 cache is
configured for Pipelined Burst SRAM with cache size 512KB in factory default. The
cacheable region can be up to 128MB cache memory configuration by using 8-bit
TAG RAM or using internal TAG SRAM to acquire cacheable region up to 512MB.
The South Bridge M1543C provides a highly integrated PCI-to-ISA bridge solution
for the best industry application. It comprises a 2-channel dedicated Ultra DMA-33
IDE master interfaces, Plug-and-Play port, and APIC interface. It also supports PS/2
keyboard and mouse controller, 2-port USB (Universal Serial Bus feature), PCI 2.1
Compliance operation, and the Super I/O function which includes two high speed
serial ports, one parallel port, FIR port, and FDD interface port.
In addition, the M1543C also provides XD-bus to support BIOS read/write access
and real-time clock (RTC) to maintain date and time of a system. A standard 16-bit
ISA bus interface is applied for all of slower I/O operations. In ROBO-598, it
contains watch-dog timer (WDT) enabled by jumper setting and trigger by software,
disk-on-chip (DOC) for M-system Flash disk, and ISA buffer for special I/O
applications and driving of multi-ISA slots. The detail operating relations are shown
in Figure 1-1 ROBO-598 System Block Diagram.
