III Processor for the PGA370 Socket at 500 MHz to 1.13 GHz
Introduction
The Intel
the Intel IA-32 processor line and hereafter will be referred to as the “Pentium III processor”, or
simply “the processor”. The processor uses the same core and offers the same performance as the
Pentium III processor for the SC242 connector, but utilizes a package technology called flip-chip
pin grid array, or FC-PGA. This package utilizes the same 370-pin zero insertion force socket
(PGA370) used by the Intel
back of the processor core package without the use of a thermal plate or heat spreader. As core
frequencies increase, the need for better power dissipation arises, so an Integrated Heat Spreader
(IHS) has been introduced at the higher frequencies near 1B GHz. The package with an IHS is
called FC-PGA2.
The Pentium III processor, like its predecessors in the P6 family of processors, implements a
Dynamic Execution microarchitecture—a unique combination of multiple branch prediction, data
flow analysis, and speculative execution. This enables these processors to deliver higher
performance than the Pentium processor, while maintaining binary compatibility with all previous
Intel Architecture processors. The processor also executes Intel
for enhanced media and communication performance just as it’s predecessor, the Pentium III
processor. Additionally, Pentium III processor executes Streaming SIMD (single-instruction,
multiple data) Extensions for enhanced floating point and 3-D application performance. The
concept of processor identification, via CPUID, is extended in the processor family with the
addition of a processor serial number. Refer to the Intel
for more detailed information. The processor utilizes multiple low-power states such as
AutoHALT, Stop-Grant, Sleep, and Deep Sleep to conserve power during idle times.
The processor includes an integrated on-die, 256-KB, 8-way set associative level-two (L2) cache.
The L2 cache implements the new Advanced Transfer Cache Architecture with a 256-bit wide bus.
The processor also includes a 16-KB level one (L1) instruction cache and 16-KB L1 data cache.
These cache arrays run at the full speed of the processor core. As with the Pentium III processor for
the SC242 connector, the Pentium III processor for the PGA370 socket has a dedicated L2 cache
bus, thus maintaining the dual independent bus architecture to deliver high bus bandwidth and
performance (see
allowing significant headroom for desktop systems. Refer to the Specification Update document
for this processor to determine the cacheability and cache configuration options for a specific
processor. The Specification Update document can be requested at your nearest Intel sales office.
The processor utilizes the same multiprocessing system bus technology as the Pentium II processor.
This allows for a higher level of performance for both uni-processor and two-way multiprocessor
systems. The system bus uses a variant of GTL+ signaling technology called Assisted Gunning
Transceiver Logic (AGTL+/AGTL) signaling technology.
