Start your Engine eight time faster that before

Up to 2x faster.

Eight-core processing power was once only top-of-the-line. Now it comes standard. This time around, performance is more phenomenal than ever — up to two times faster than the previous standard-configuration Mac Pro.¹ And with the multicore technology enhancements of Mac OS X Leopard, the new Mac Pro is a force to be reckoned with.

More power with less power.

Inside the new Mac Pro is the latest technology from Intel: Quad-Core Intel Xeon “Harpertown” processors. These processors run at blazingly fast speeds up to 3.2GHz. Based on the new 45-nm Intel Core microarchitecture, they deliver amazing performance but still maintain outstanding energy efficiency.

Cache count.

A huge amount of L2 cache — 12MB per processor — keeps frequently used data and instructions close to the processor cores and improves overall performance. 6MB of cache is shared between pairs of processor cores, allowing an individual core to use all the available shared cache at any one time.

Built at full tilt.

With the fastest Xeon architecture available, the new Mac Pro features 1600MHz dual independent frontside buses. These 64-bit buses give each processor a direct connection to the system controller and deliver improved processor bandwidth of up to 25.6GB per second — 20 percent greater than the previous Mac Pro. With a new system architecture, speedier system buses, and fast 800MHz DDR2 fully buffered DIMM memory, Mac Pro memory throughput is up to 1.6 times faster than before.

Dual-processor, Dual-core, and Multi-core: Keeping it straight

Dual core (DP) systems are those that contains two separate physical computer processors in the same chassis. In dual-processor systems, the two processors can either be located on the same motherboard or on separate boards.  In a dual-core configuration, an integrated circuit (IC) contains two complete computer processors. Usually, the two identical processors are manufactured so they reside side-by-side on the same die, each with its own path to the system front-side bus. Multi-core is somewhat of an expansion to dual-core technology and allows for more than two separate processors.

For software to take advantage of dual core architecture, it must be written to utilize parallel threading. Otherwise, the program functions in single-core mode, using just one data stream or one of the built-in microprocessors. Unfortunately, coding for TLP is quite intensive, as interleaving shared data can create errors and slow performance. Because of these and other issues, a dual core processor does not deliver twice the speed of a single-core processor, though there is a significant increase in performance under optimal conditions. Finally, dual core chips run hotter than their single-core cousins.

What is Symbian OS? How does Symbian OS work

What is Symbian OS?

Symbian OS (operating system) is an operating system designed specifically for mobile devices. It is being developed by Symbian Ltd, a software licensing company that supplies the operating system for many data-enabled mobile phones.

How does Symbian OS work?

As an operating system software, Symbian OS provides the underlying routines and services for application software. For example, an email software that interacts with a user through a mobile phone screen and downloads email messages to the phone’s inbox over a mobile network or WiFi access, is using the communication protocols and file management routines provided by the Symbian OS.

Symbian OS technology has been designed with these key points in mind:

• to provide power, memory and input & output resource management specifically required in mobile devices
• to deliver an open platform that complies with global telecommunications and Internet standards
• to provide tools for developing mobile software for business, media and other applications
• to ensure the wide availability of applications and accessories for different user requirements
• to facilitate wireless connectivity for a variety of networks

About Symbian OS

Nokia has made Symbian OS its strategic choice for smartphone operating systems. Nokia S60 Software, currently the most widely used software platform in the smartphone market worldwide, runs on Symbian OS - as does the advanced Nokia Series 80 Communicator devices. The Symbian OS-based Nokia Series 90 platform delivers touch screen technology and an advanced software development environment for media-rich applications.

What are the benefits of Symbian OS?

• Wide selection of applications available for a range of mobile phones
• Implements industry standard protocols, interfaces and management services for IT system integration
• Application development using industry standard Java and C++ languages
• Extensive connectivity options - including GSM, GPRS, CDMA, WCDMA, WiFi and Bluetooth
