1.3History

Not that long ago, competition in the microprocessor world centred on x86 designs for desktop PCs and RISC devices for workstations. “In the 1990s, [CPU design] was all about performance – nobody cared about power consumption or how much it cost,” said Linley Gwennap, principal analyst of The Linley Group. But, as the market matured, x86 players either left the market or were acquired, leaving Intel and AMD to fight it out.

Today, it is the mobile computing market that is fiercely contested, especially processors for smartphones and sub notebooks – a computer class known variously as mobile internet devices, netbooks or smartbooks.

“With mobile processors, it is not just the processor, but also 3d graphics, audio and video processing and cellular, all designed with an incredibly low power budget and constrained cost,” said Gwennap. For Gwennap, mobile processors are driving semiconductor innovation. “Mobile processors are the hardest design task to take on – the same performance as a pc crammed onto one chip,” he said.

Qualcomm’s Snapdragon is one such device and is already used to power Google’s high profile Nexus One Smartphone. Qualcomm has several Snapdragon ICs based on the ARM Cortex-A8 instruction set and plans to adopt the design across more of its product families.

Snapdragon’s origins date back five years when Qualcomm brought onboard a low power PowerPC processor design team released by IBM. “We hired the team intact,” said Mark Frankel, vice president of product management at Qualcomm’s CDMA Technologies division. The team began designing its ARM based core with a target clock speed of at least 1GHz.

Five years on, several Snapdragon designs exist. The first, now shipping in Smartphone and smartbook products, is the 65nm 1GHz QSD8250/8650. “The QSD8250 and 8650 is the same silicon,” said Frankel. “The difference is the Firmware: the 8250 is UMTS only, while the 8650 is multimode and supports CDMA-2000.”

Two follow on 45nm Snapdragon designs have been detailed: the QSD8650A, clocked at 1.3GHz, and the dual core QSD8672, clocked at up to 1.5GHz. Qualcomm owns an ARM architectural license, such that while Snapdragon is code compatible with ARM’s Cortex-A8, the company has freedom to design its own hardware. The result is an ARM7 compatible superscalar processor with a 128bit single instruction, multiple data (SIMD) engine, dubbed VeNum, instead of ARM’s 64bit NEON

“We can dispatch instructions with a greater throughput than a typical ARM, and we control the [memory] caches and where we put them,” said Frankel. “Not only do we have control of the process and transistor mix, but also the [technology’s] creative design.”

In addition to the SIMD engine, Snapdragon includes a dsp and a graphics unit. The QSD8250’s 600MHz dsp is Qualcomm’s own design and performs mainly video processing. The device can encode and decode video at a 720p rate and includes dedicated hardware blocks. The faster QSD8672 is able to process video at 1080p.

Given the dedicated dsp, why is the SIMD engine – ideal for multimedia processing needed? The answer is to run multimedia codecs, such as flash, written by third parties. In contrast,

4-38

Snapdragon

the dsp, with its own microcode, was never designed to be programmed by Snapdragon based product developers, says Frankel.

The 2d/3d graphics engine is the result of Qualcomm’s acquisition of the assets of an ATI supports the faster data rate HSPA+. The 3G modem is a core advantage of Qualcomm’s integrated device. “As a leader in 3G cellular, if designers choose the Snapdragon, they know they are getting a solid 3G baseband used around the world,” said Gwennap

To constrain the Snapdragon’s power consumption – and hence prolong a mobile device’s battery operating life – functional blocks are clocked independently. “The power can also be switched down within a clock cycle and when you need processing, it can be switched on almost instantly,” said Frankel. The 65nm 1GHz QSD8650 device consumes 0.5W and has a standby rating of 10mW. The 45nm process unit, whose graphics core Qualcomm had licensed previously.

“The 3d graphics is extremely important [for Smartphones and smartbooks]; it is the first [product] impression a user gets,” said Frankel

The 3d graphics performance of the QSD8650 is 22million triangle/s and 133m 3d pixel/s. It also supports displays of up to WXGA (1366 x 768). The QSD8672 extends performance to 80m triangle/s and more than 500m 3d pixel/s. Display capability is extended to WSXGA (1440 x 900).

As for Snapdragon’s integrated wireless modem, the QSD8650/A supports UMTS, including the high speed packet access standard (HSPA),as well as CDMA-2000, while the QSD8762 also reduces the power consumption to 0.35W for the QSD8650A.

Qualcomm claims 15 manufacturers are now developing 40 designs based on the Snapdragon. First to be announced was the Toshiba TG01 smartphone. Since then, other smartphone product launches include such firms as HTC, Acer, Sony Xperia and LG

In January, Qualcomm announced that Lenovo is developing several designs, including a smartbook to be launched by US operator AT&T.

This will be followed by launches in China and Europe. Qualcomm is also working with HP on a Snapdragon based Android smartbook. There is a lack of rigour when it comes to describing mobile computing devices; even experts agree that definitions are ‘slippery’

Meanwhile, the Google Nexus One handset is the fastest clocked smartphone on the market. Qualcomm’s mix of design wins spans leading smartphone and smartbook makers. But, by integrated a powerful cpu with a cellular modem, the design is confined to applications that require both functions.

“It is not the device for navigation devices or media players, unless mobile functionality is also needed,” said Gwennap. This is in contrast with the likes of Texas Instruments, whose OMAP processor is targeted at several products. “The good news for Qualcomm is that cellular is popping up in a lot of places, such as e-books, while a lot of netbooks are sold with cellular functionality included,” said Gwennap.

Snapdragon faces stiff competition from the likes of Marvell and Free scale (see NE, 23 Feb 2009), as well as from Intel and Nvidia. While ARM’s Cortex-A8 may not be clocked at 1GHz, ARM continues to invest heavily in its architecture and has announced the Cortex-A9

CPU, which has architectural enhancements such as instruction reordering. This will give a processing edge for the same clock speed as the Snapdragon.

According to Linley Group, the Cortex-A9 cpu will ship in Nvidia’s Tegra 250 in the second quarter of 2010. Tegra 250 contains two Cortex- A9 CPUs; each running at up to 1GHz. Texas Instruments’ OMAP4 also uses ARM’s Cortex-A9 and will ship later this year.

3.3 Smartbooks

Fig.3.2 Smartbooks

The new breed of hybrid Smartphone and netbook called the smartbook. It is made by Lenovo and it runs on Qualcomm (NSDQ: QCOM)’s Snapdragon processor and Linux software. Qualcomm’s chief executive Paul Jacobs flashed the device at an analysts meeting in New York. Qualcomm has long championed the category it calls the smartbook. It’s a cross between the netbook and the Smartphone; the idea is to combine the best of both devices in one. However, some Smartphones are already sporting the features trumpeted in smartbooks. Smartbooks are touted by manufacturers for the same features found in some advanced smartphones technology, as well as superior energy efficiency. While Qualcomm didn’t formally launch the smartbook, it has revealed improvements in its Brew Mobile Platform OS that should help independent developers bring their smartbook models to market faster. The firm said key software components are being integrated in the Brew platform including Java virtual machine browsers, multimedia, instant messaging, and calendar applications. Qualcomm said that the new features will enable device developers to distribute applications before new handsets are launched. “Qualcomm is working closely with key software technology providers,” said Jason Kenagy, VP of product management for Qualcomm Technologies, in a statement. “This effort includes optimization of target devices and pre-distribution of these products to device makers.”

3.4 Future Progress

As mobile applications become more demanding, and networks become faster and more capable of handling heavy data loads, smartphones will continually push the limits of what is possible on a mobile device while still ensuring a good user experience. Mobile performance, power optimisation, connectivity options, and device size remain critical to the success of smartphones. Cost-efficiency will also dictate how accessible devices are in various markets.

In early January, Lenovo announced their Skylight product, which is the first Snapdragon notebook. Right now, there are 15 manufacturers developing more than 40 Snapdragon-based devices, including smartphones and smartbooks. From the inception of Snapdragon several years ago, Qualcomm believed that mobile devices would continue to evolve to become more capable and more valuable to everyday life. This included not only groundbreaking new smartphones, but devices with larger displays. We therefore began work on the custom central processor that is at the heart of Snapdragon, which enables it to deliver performance exceeding 1 GHz and with low levels of power consumption.

The Lenovo Skylight is a 10 in (25 cm) mobile HD device which uses a 1 GHz Snapdragon processor.

The soon to be released LG eXpo and the Sony Ericsson XPERIA X10 are also being built using a 1 GHz Snapdragon processor.

Acer Liquid is the first mobile phone to use this Qualcomm Snapdragon.

Soon to be released Nokia N900 is also using snapdragon 1GHz chipsets with Maemo OS.

Snapdragon

Advancements in mobile connectivity have coalesced, bringing us to the brink of a major new mobile paradigm. What will the next generation of mobile technologies look like? Qualcomm is seizing a leadership position in bringing such new opportunities to market. On Qualcomm's groundbreaking Snapdragon platform, powerful processors and long battery life peaceably coexist, creating a more mature and always connected experience.

To make the point clearer, let's tell a story about an everyday college student. Let's call him Dan.

Fig.4.1 Use of Snapdragon in Mobile computing devices

Dan wakes up in the morning and gets ready to go to class. While eating breakfast, he streams the latest tunes from his favourite music blogs and compiles them into a fresh playlist for the day.

As Dan carpools to class, he updates his presentation for Polisci 102 from the backseat. Meanwhile he checks real-time traffic conditions to find out which campus parking lots still have space available and passes the data to his friend in the driver's seat.

After his presentation, Dan has an interview with the Dean for his college paper. Instead of fidgeting with his notes and trying to scribble down a legible shorthand, Dan simply films his conversation with the Dean. He uses the footage from his interview as a transcript for the printed edition of his paper and then posts the raw video in a web blog.

Once he is done with his classes, Dan finds himself waiting for his roommate in the parking lot. He uses the downtime to check his grades, and then to research the scheduled nightlife at area clubs that evening. Stopping by the supermarket before going home, Dan and his roommate find a great deal on sundried tomatoes. They don't really know what to make with sundried tomatoes, but Dan quickly uses his mobile device to find a suitable recipe.

After dinner, Dan hits the city to go dancing. At the club, he hears a few songs that he likes; he takes note of their titles so he can check them out later. Dan also shows off all his photos

and video clips to his friends, letting everyone see the evidence of his fantastic trip to South America last month.

After the club, Dan finds out where the cheapest late night food is and gets some quick sustenance before heading home for the night.

How did Dan accomplish all of this? Not with a laptop or cell phone. No, Dan has found a smarter and more modern solution. He uses a Snapdragon-based device.

Qualcomm's groundbreaking Snapdragon platform doesn't sacrifice mobility for processing power or battery consumption. It creates a rich media, always-connected experience. A Snapdragon-based device is a tool to fill the gaps in your life.

The options for mobile connectivity are opening up in ways we never dreamed possible five years ago. Thanks to the revolutionary Snapdragon platform, the question isn't what you want to do; the question is how far you want to take it.

4.2 First Linux support for Snapdragon

Qualcomm has announced three Scorpion-based MSM8xxx mobile chipsets that target high-end devices with HD 1080p video. The devices are said to be equipped with Scorpion processors clocked up to 1.2GHz (Scorpion, like ARM's own Cortex, implements ARM's

ARMv7 architecture). Although the company did not initially brand them as "Snapdragon" processors, they are touted as being "pin-, software-, and functionality-compatible" with Qualcomm's earlier Snapdragon chips, the QSD8250 and QSD8650. Xandros did not mention a specific brand of Snapdragon, but is likely targeting this newer MSM8xxx platform.

The Snapdragon architecture first appeared in the QSD8250 and QSD8650 chipsets, announced in 2007. Those chips were recently used in a Windows Mobile-based smartphone from Toshiba called the TG01. Qualcomm's QSD8250 offers an ARM-based "Scorpion" CPU clocked at 1GHz, plus a 600MHz DSP (digital signal processor). The platform also provides an integral GPS receiver, day-long battery life, HD video playback, and support for cameras up to 12 megapixels, according to Qualcomm. Other Snapdragon support is said to include HSDPA (high speed downlink packet access) connectivity, WiFi, and Bluetooth. The QSD8650 is similar to the QSD8250 except for the addition of dual-mode support for providing both HSPA and CDMA2000 1xEV-DO Rev. B connectivity.

4.3 Devices using Snapdragon

The first mobile internet device to use a 1 GHz Snapdragon was Toshiba’s TG01 Smartphone. This was shortly followed by Acer's neoTouch.

In 2009 HTC Corporation used the QSD8250, 1GHz chipset in the HTC HD2.
