Function
Additional Address Status. This signal is mainly used for large or standalone L2
cache memory subsystem support required for high-performance desktop or
server models.
Additional Burst Ready. This signal is mainly used for large or standalone L2
cache memory subsystem support required for high-performance desktop or
server models.
CPU Type. This signal is used for dual processing systems.
Dual/Primary processor identification. This signal is only used for an Upgrade
processor.
Functional Redundancy Checking. This signal is only used for error detection
via processor redundancy, and requires two Pentium processors
(master/checker).
Private Bus Grant. This signal is only used for dual processing systems.
Private Bus Request. This signal is used only for dual processing systems.
Private Hit. This signal is only used for dual processing systems.
Private Modified Hit. This signal is only used for dual processing systems.
The I/O buffer models provided in section 4.4 of this
document apply to both the Pentium processor
(610\75) TCP and SPGA packages, although the
capacitance (Cp) and inductance (Lp) parameter
values differ between the two packages. Also, the
thermal parameters, TCASE max and θCA, differ
between the TCP and SPGA packages. For
Pentium processor (610\75) SPGA values, refer to
Chapters 24 and 26 of the Pentium® Processor
Family Developer’s Manual, Volume 1 .
2.0. MICROPROCESSOR
ARCHITECTURE OVERVIEW
The Pentium processor at iCOMP® rating 610\75
MHz extends the Intel Pentium family of
microprocessors. It is compatible with the 8086/88,
80286, Intel386â„¢ DX CPU, Intel386 SX CPU,
Intel486â„¢ DX CPU, Intel486 SX CPU, Intel486
DX2 CPUs, the Pentium processor at iCOMP Index
510\60 MHz and iCOMP Index 567\66 MHz, and
the Pentium processor at iCOMP Index 735\90
MHz and iCOMP Index 815\100 MHz.
The Pentium processor family consists of the new
Pentium processor at iCOMP rating 610\75 MHz,
described in this document, the original Pentium
processor (510\60, 567\66), and the Pentium
processor (735\90, 815\100). The name "Pentium
2
processor (610\75)" will be used in this document to
refer to the Pentium processor at iCOMP rating
610\75 MHz. "Pentium Processor" will be used in
this document to refer to the entire Pentium
processor family in general.
The Pentium processor family architecture contains
all of the features of the Intel486 CPU family, and
provides significant enhancements and additions
including the following:
• Superscalar Architecture
• Dynamic Branch Prediction
• Pipelined Floating-Point Unit
• Improved Instruction Execution Time
• Separate 8K Code and 8K Data Caches
• Writeback MESI Protocol in the Data Cache
• 64-Bit Data Bus
• Bus Cycle Pipelining
• Address Parity
• Internal Parity Checking
• Execution Tracing
• Performance Monitoring
• IEEE 1149.1 Boundary Scan
• System Management Mode
