Processor/Memory Subsystem
Figure 3-2 illustrates the basic internal architecture of an Intel Pentium single-core processor.
Dual-core processors feature two cores operating in parallel. The table below provides a
representative listing of supported processors. Other models may also be supported.
Figure 3-2. Supported Pentium and Core 2 Duo Processors (partial listing)
The Intel Pentium processor increases processing speed by using higher clock speeds with
hyper-pipelined technology, therefore handling significantly more instructions at a time. The
Arithmetic Logic Units (ALUs) of all processors listed above run at twice the core speed.
An improved branch prediction mechanism features an execution trace cache and a refined
prediction algorithm. The execution trace cache can store 12 kilobytes of micro-ops (decoded
instructions dealing with branching sequences) that are checked when re-occurring branches are
processed. Code that is not executed (bypassed) is no longer stored in the L1 cache as was the
case in earlier generation Pentium processors.
The Pentium processor is compatible with software written for x86 processors. These systems
also support the Intel Celeron D processors and the energy-efficient Intel Core
