Architecture
CPU Chip
The Intel Pentium III processor integrates P6 Dynamic Execution microarchitecture, Dual
Independent Bus (DIB) Architecture, a multi-transaction system bus, Intel MMX™ media enhancement technology, and the Intel Processor Serial Number. In addition, it offers
Internet Streaming SIMD Extensions, 70 new instructions enabling advanced imaging,
3D, streaming audio and video, and speech recognition. The Intel Pentium III processor
also has two16 KB L1 caches, instruction and data, and one 256 KB Advanced Transfer Cache (full speed, synchronous L2 cache with Error Correcting Code). The Pentium III
processor supports a 100 Mhz front-side bus.
The Intel Celeron Processor integrates P6 Dynamic Execution microarchitecture and Intel
MMX™ media enhancement technology. The Celeron processor also has two16 KB L1
caches, instruction and data, and one 128 KB unified, non-blocking L2 cache. The Celeron processor supports a 66 Mhz front-side bus.
Onboard Memory
SDRAM Memory
The XVME-660 has a socket for a single 144-pin SODIMM, providing up to 256 MB of
SDRAM. The XVME-660 configurations include 32 MB, 64 MB, 128 MB, and 256 MB.
Approved SDRAM suppliers are listed in Appendix A.
Flash BIOS
The XVME-660 system BIOS is contained in a 512 KB flash device to facilitate system
BIOS updates.
Boot ROM Site
This 32-pin onboard site is used during manufacture to flash the BIOS with a boot ROM.
This site should not be used during normal operation.
