3.4.3. Single Board Computer Main Features
The PCI-946-1 and P3S440BX are powerful computing engines. In addition to the CPU
core, it is supplemented by an extensive set of interfaces using five key components:
3.4.4. Celeron and Pentium
The PCI-946-1 SBC support the Intel's Celeron 300AMHz, 366MHz, 433MHz and
566MHz. The P3S440BX support the Intel's low power Pentium® III processor running at
600MHz 700MHz (higher clock speeds will be available when Intel releases the
corresponding parts).
The PCI-946-1 SBC consists of a Celeron processor core with an integrated second level
cache of 128KB (on-die, full CPU speed, ECC capable) and a 64-bit high performance
66MHz front side bus.
The P3S440BX SBC consists of a Pentium
level cache of 256KB (on-die, full CPU speed, ECC capable) and a 64-bit high
performance 66/100MHz front side bus.
The processor interfaces to the 440BX AGPset through the 64-bit low power GTL + data
bus interface.
3.4.5. North Bridge Chipset
This chipset consist of 443BX AGPset, 64/72-bit SDRAM data interface with ECC
support, Low Power GTL Bus, five PCI arbitration channels, PCI bus rev. 2.1, Accelerated
Graphics Port Interface (AGP). The bus is optimized for 100MHz operation.
