MICROPROCESSOR
ARCHITECTURE OVERVIEW
The Pentium
processor with MMX technology
extends the Intel Pentium family of microprocessors.
It is binary compatible with the 8086/88, 80286,
Intel386 DX, Intel386 SX, Intel486 DX, Intel486
SX,
Intel486
DX2
and
60/66/75/90/100/120/133/150/166/200.
Pentium
processors
The Pentium processor family currently includes the
following products.
Pentium processor with MMX technology:
Pentium processor with MMX technology at
233 MHz, iCOMP
Index 2.0 rating = 203
Pentium processor with MMX technology at
200 MHz, iCOMP Index 2.0 rating = 182
Pentium processor with MMX technology at
166 MHz, iCOMP Index 2.0 rating = 160
Pentium processor 133/150/166/200. The name
"Pentium processor 133/150/166/200" will be
used in this document to refer to the Pentium
processor with 133, 150, 166 and 200 MHz
versions of the Pentium processor:
Pentium processor at 200 MHz, iCOMP
Index 2.0 rating = 142
Pentium processor at 166 MHz, iCOMP
Index 2.0 rating = 127
Pentium processor at 150 MHz, iCOMP
Index 2.0 rating = 114
Pentium processor at 133 MHz, iCOMP
Index 2.0 rating = 111
Pentium processor at 120 MHz, iCOMP
Index 2.0 rating = 100
Pentium processor at 100 MHz, iCOMP
Index 2.0 rating = 90
Pentium processor at 90 MHz, iCOMP Index
2.0 rating = 81
Pentium processor at 75 MHz, iCOMP Index
2.0 rating = 67
The Pentium processor family supports the features
of previous Intel Architecture processors, and
provides significant enhancements and additions
including the following:
Superscalar Architecture
Dynamic Branch Prediction
Pipelined Floating-Point Unit
Improved Instruction Execution Time
Separate Code and 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
Virtual Mode Extensions
Dual processing support
On-chip local APIC device
In addition to the features listed above, the Pentium
processor with MMX technology offers the following
enhancements over Pentium processor 133/150/
166/200:
Support for Intel MMX technology
Doubled code and data cache sizes to 16 KB
each
Improved branch prediction
Enhanced pipeline
Deeper write buffers
The following features are supported by the Pentium
processor 133/150/166/200, but these features are
not supported by the Pentium processor with MMX
technology:
Functional redundancy check and Lock Step
operation.
Support for Intel 82498/82493 and 82497/82492
cache chipset products
Split line accesses to the code cache
