New Atom Z6 Positions Intel for Phone, Tablet Push ARTICLE DATE: 05.05.10 By Matthew Murray Intel's Atom processor revolutionized the computer industry a few years ago when it essentially created a new category of systems: the netbook. Lightning can't strike twice today with Intel's announcement of its new Atom Z6 processor and supporting platform, as the kinds of systems they're designed to drive —smartphones and tablets —are already well established in the market. But the CPU does signal Intel's serious intention to dominate mobile the way it does traditional PCs. Intel has based the Atom Z6 CPU family (formerly code-named "Lincroft") on its new high-K 45nm 2 LP process. The CPU, which has 512KB of L2 cache, and 24KB of data and 32KB of instruction cache on L1), has 140 million transistors packed into the System on Chip (SoC). The Z6 is designed for both smartphones and more traditional tablets, but Intel hopes that the phone is where the platform, based on the traditional X86 architecture, eventually ends up. The new Lincroft chip (part of a platform Intel calls "Moorestown") supports up to 1.5 GHz for high-end smartphones and up to 1.9 GHz for tablets and other handheld designs. "Intel has delivered its first product that is opening the door for Intel Architecture [IA] in the smartphone market segment," said Anand Chandrasekher, Intel senior vice president and general manager of the Ultra Mobility Group, in a statement. "Through 'Moorestown,' Intel is scaling the benefits of IA while significantly reducing the power, cost and footprint to better address handheld market segments. As a result of our efforts, the Intel Atom processor is pushing the boundaries of hi gher performance at significantly lower power to show what's possible as handheld devices become small, powerful mobile computers." The Moorestown platform has a heavy emphasis on video, with an integrated and power- optimized Intel GMA 600 Graphics system. A core frequency of up to 400 MHz is supported, as are OpenGL ES2.0, 2.1, and Open VG 1.1. Hardware-accelerated HD video encoding (MPEG-4 part 2, H.264) and decoding (MPEG-4 part 2, H.264, WMV, and VC1) are also on hand. The maximum display resolution is 1,366 by 768 LVDS or 1,024 by 600 MIPI. There's also an integrated 32-bit single-channel memory controller, with support for LPDDR1 200 MHz (a rate of 400 MTps) up to 1GB or DDR2 400 MHz (800 MTps) up to 2GB. Despite all these capabilities, Intel estimates that, compared to its first-generation Atom CPUs, the Atom Z6 uses up to 50 times less power when idling, 20 times less when performing audio functions, and 2 to 3 times less during Web browsing and video watching. Intel claims that these savings can result in more than 10 days of battery life in standby, up to 2 days when playing back audio, and 4 to 5 hours of Web browsing and video.

Intel's Atom processor revolutionized the computer industry a few years ago when it essentiallycreated a new category of systems: the netbook. Lightning can't strike twice today with Intel'sannouncement of its new Atom Z6 processor and supporting platform, as the kinds of systemsthey're designed to drive—smartphones and tablets—are already well established in the market.But the CPU does signal Intel's serious intention to dominate mobile the way it doestraditional PCs.
Intel has based the Atom Z6 CPU family (formerly code-named "Lincroft") on its new high-K45nm2 LP process. The CPU, which has 512KB of L2 cache, and 24KB of data and 32KB ofinstruction cache on L1), has 140 million transistors packed into the System on Chip (SoC).
The Z6 is designed for both smartphones and more traditional tablets, but Intel hopes that thephone is where the platform, based on the traditional X86 architecture, eventually ends up. Thenew Lincroft chip (part of a platform Intel calls "Moorestown") supports up to 1.5 GHz for high-endsmartphones and up to 1.9 GHz for tablets and other handheld designs.
"Intel has delivered its first product that is opening the door for Intel Architecture [IA] in the smartphonemarket segment," said Anand Chandrasekher, Intel senior vice president and general manager of the UltraMobility Group, in a statement. "Through 'Moorestown,' Intel is scaling the benefits of IA while significantlyreducing the power, cost and footprint to better address handheld market segments.

These power improvements build on the C6 state in the original Atom processor design, with theZ6's SoC incorporating new S0i1 and S0i3 ultra-low-power states, taking the SoC to 100microwatts. A new software-based OS power management approach, called Intel Smart PowerTechnology (SPT), is responsible for the drops in power usage in idle and active states: It "appliesaggressive power and clock gating across the SoC's power islands and system voltage rails,"according to Intel.
Intel also touts the family's improved compute performance (1.5 to 3 times higher), fasterJavaScript rendering (a fourfold speed increase), and 2 to 4 times better graphics, as well assupport for 1080p HD video decoding (see above) and 720p video recording; and BurstPerformance Technology, which lets the processor dynamically burst to higher performance forshort periods of time without affecting the TDP.
The chip's MP20 Platform Controller Hub (code-named "Langwell") supports what Intel calls "arange of system-level functions and I/O blocks." These include a NAND controller; a low-power,24-bit audio engine called Intel Smart Sound Technology (SST), which enables voice processingand supports audio codecs like MP3, AAC-LC, HE-AAAC (v1 and v2), VMA9, and PCM; a high-resolution camera; USB and USB On-the-Go (OTG), the latter for helping smartphonescommunicate with other devices such as cameras, printers, or portable hard drives; securityblocks, and wireless, as well as board-level functions and Intel's Smart & Secure securityarchitecture.
A dedicated Mixed Signal IC (aka MSIC, and originally code-named "Briertown") integrates powerdelivery and battery charging; and consolidates analog and digital components such as audiocodecs, a touch screen controller, sensors, LDOs, DC-DC, and GPIOs. The MSIC is one of thekey ways the Atom Z6 family achieves such a low-power status: It enables power gating through aseries of voltage rails to the processor and PCH, and by shutting down transistors that aren't inuse can reduce power leakage and increase battery life. Per press notes, it also "enables fastertransitions in and out of power states, allow for more frequent and longer residency in ultra-low-power saving states."
The Atom Z6 family of chips is available today. The platform supports scalable frequenciesranging up to 1.5 GHz for high-end smartphones and up to 1.9 GHz for tablets and other handhelddesigns; and include support for Wi-Fi, 3G/HSPA, and WiMAX. The technology supports a rangeof software platforms, including Android, Moblin 2.1, and MeeGo 1.0. Intel also claims to be"working with leading industry players to support a breadth of middleware and applications," suchas Adobe's Flash and AIR, Microsoft Silverlight, and more.
