ZMS-08 StemCell processor

The ZMS-08 StemCell processor from ZiiLABS delivers 1080p Blu-ray quality H.264 decodes to low-power devices.

The ZMS-08 is the third generation media processor from the company, delivering more than 4x the performance of previous generation devices. The ZMS-08 combines the flexible multiformat media processing capabilities of ZiiLABS' StemCell Computing array with a 1GHz ARM Cortex processor.

Aimed at connected devices such as Web tablets, netbooks, connected TVs, video conferencing systems or home media hubs, the chip is supported by ZiiLABS' optimised Linux-based Android and native Plasma OS and development platforms.

The IC's StemCell Computing array provides the media processing capabilities to deliver full HD 1080p high-profile H.264 video decode, simultaneous H.264 encode and decode at 720p, 1080p 24fps encode, accelerated OpenGL ES 2.0 3D graphics at up to 1Gpixel/s, 2D processing, compositing, image processing and advanced Xtreme Fidelity X-Fi Audio effects.

With the low-power ARM Cortex processor running at up to 1GHz, the ZMS-08 is aimed at small form factor devices that enable content currently accessed via the PC to spread to mobile and low-energy devices.

The StemCell Computing array features 64 fully programmable floating point processing elements that off-load the media processing from the ARM CPU.

The tightly coupled 1GHz ARM Cortex-A8 provides a secure, high performance main CPU that features a 256K L2 cache, NEON, TrustZone security technology and 1GB addressable RAM.

A wide range of integrated peripheral functions help to reduce system costs, complexity and device footprint. Dual USB 2.0 OTG controllers with PHY and ULPI interfaces provide direct connection to USB hosts, peripherals and high-speed modems.

Four HD video processing units support camera and display input and output processing with the integrated HDMI and analogue video encoders supporting HD-TV 1080p output at 60fps.

The secure Boot ROM, three SDIO/MMC ports, UARTs, SPI, GPIO and advanced 64-bit and 32-bit memory controller supporting mDDR and DDR2 at up to 333MHz provide the interfaces and memory bandwidth required for today's media rich connected devices.

The ZMS-08 is sampling to certain customers now and is scheduled for volume shipment in the 1st quarter of 2010. The chip is housed in a 13mm x 13mm, 424-pin FBGA package.
