System Processors
Each Pentium III Xeon processor is packaged in a single edge contact (S.E.C.) cartridge.
The cartridge includes the processor core with an integrated 16 KB primary (L1) cache;
the secondary (L2) cache; a thermal plate; and a back cover.
The processor implements the MMX technology and it has a numeric coprocessor that
significantly increases the speed of floating-point operations and complies with
ANSI/IEEE standard 754-1985.
Each S.E.C. cartridge connects to the processor board through a 330-pin Slot 2 edge
connector. The cartridge is secured by a retention module attached to the processor
board. Depending on configuration, your system has one to four processors.
The processor external interface is MP-ready and operates at 100 MHz. The processor
contains a local APIC unit for interrupt handling in multiprocessor (MP) and
uniprocessor (UP) environments.
The L2 cache is located on the substrate of the S.E.C. cartridge. The cache:
• Includes burst pipelined synchronous static RAM (BSRAM)
• Is offered in 512 KB, 1 MB, and 2 MB configurations
• Has error checking and correction (ECC)
• Operates at the full core clock rate
