System Overview 1-7
Pentium II Processor
Depending on system configuration, each system includes one or two
Pentium II processors. Each Pentium II 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 the processor’s numeric
coprocessor significantly increases the speed of floating-point
operations.
The processor external interface operates at 100 MHz. The second-level
cache is located on the substrate of the S.E.C. cartridge. The cache
includes burst pipelined synchronous static RAM (BSRAM). The L2
cache is offered in 512 KB configurations only, with error correcting
code (ECC) that operates at half the core clock rate.
System Memory
The system board contains four 168-pin DIMM sockets. Memory is
partitioned as four banks of SDRAM DIMMs, each providing 72 bits of
noninterleaved memory (64-bit main memory plus ECC). Your system
may include from 32 MB to 1 GB of memory, using up to four DIMMs.
System memory begins at address 0 and is continuous (flat addressing)
up to the maximum amount of DRAM installed (exception: system
memory is noncontiguous in the ranges defined as memory holes using
configuration registers). The system supports both base (conventional)
and extended memory.
