Processor Each Pentium II 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 maintains full backward compatibility with the 8086, 80286, Intel386™, Intel486™, Pentium, and Pentium Pro processors. The processor's numeric coprocessor significantly increases the speed of floating-point operations and complies with ANSI/IEEE standard 754-1985. Each S.E.C. cartridge connects to the baseboard through a 330-pin Slot 2 edge connector. The cartridge is secured by a retention module attached to the baseboard. 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 ECC • Operates at the full core clock rate 21
