Description of an example model and discuss it properties and technology?


Intel Core 2 Duo


Core 2 Duo properties sporting up to 2.93GHz clock speeds and a 4 MB shared L2 cache. Overall, Core 2 Duo is a powerful processor that undoubtedly act as a type of solvent to remove the stains accumulated on Intel's armor throughout its Netburst days, and specifically those towards the end with Prescott.
The Core 2 architecture brings some really exciting additions Technologys to Intel's processor core.
These are:
1. Wider execution (now four-way instead of three-way)2. Smart Memory Access3. Advanced Smart Cache4. Advanced Digital Media Boost5. Virtualization6. EM64T7. Execute Disable Bit8. 14-stage pipeline (or less)

The CPU combines two independent cores working in parallel within the same packaging. These cores work at the same clock speed and share 2MB L2 cache. They are connected to the chipset using the same Quad Pumped Bus working at 1066MHz frequency and featuring 8.5GB/s bandwidth.
* Intel Wide Dynamic Execution . Each of the two processor cores can process four instructions per clock cycle.
* Intel Smart Memory Access . The enhanced data prefetch mechanism allows to reduce the idling time of the processor execution pipeline.
* Intel Advanced Smart Cache . Intellectual L2 cache is shared between the two processor cores depending on their load at the given moment of time. Moreover, the shared L2 cache speeds up data transfer rate between the cores and reduces the front side bus workload, because no data needs to be transferred via the system memory any more.
* Intel Advanced Media Boost . The processor works faster with SSE3 instructions because it can perform the binary operations with 128-bit SSE registers within one clock cycle.
* Intel Virtualization Technology (Intel VT) . This virtualization technology allows modeling the work of several virtual platforms on a single hardware system.
* Intel Enhanced Memory 64 Technology (Intel EM64T) . The processor supports x86-64 extensions that allow addressing over 4GB of system RAM and support the work with 64-bit general purpose registers.
* Execute Disable Bit . The OS is protected against harmful spyware and viruses that use “buffer overflow” error to gain control over the system.

* Lower heat dissipation and power consumption . Core 2 Duo processors are manufactured with the newest 65nm technological process.
