Already the familiar voice phone is being transformed into a personal device with a wide range of multimedia capabilities. Soon mobile users will be able to benefit from a broad spectrum of multimedia features and services, to include capturing, sending and receiving images, videos and music. To deliver such data-heavy, processing-intensive services, portable handheld systems must be optimized for high performance but low power, space and cost. In response to this need, the STN8815 processor platform from STMicroelectronics is a culmination of breakthroughs in video coding efficiency, inventive algorithms and chip implementation schemes. It will enable smart phones, wireless PDAs, internet appliances and car entertainment systems to play back media content, record pictures and video clips, and perform bidirectional audio-visual communication with other systems in real time. The STN8815 focuses on the essential features to meet the future needs of mobile products and services: a high-performance multimedia capability coupled with low power consumption, and based on an open platform strategy.

Main features The STN8815 processor platform enables compelling multimedia applications by means of its unique distributed-processing architecture. The application processor features low-power smart accelerators which handle all audio, video and graphics functions. These free the main CPU for control and program flow tasks, or allow the CPU to enter power-saving modes to prolong battery life. The smart accelerators operate independently and concurrently to ensure the lowest absolute system power and deterministic high-performance. The main features of the platform are: A smart video accelerator for SDTV video encoding and decoding, with MIPI and SMIA camera interfaces. A smart audio accelerator containing a comprehensive set of digital audio decoders and encoders, and offering a large number of 3-D surround effects. A smart imaging accelerator, providing real-time, programmable image reconstruction engine. A smart graphics accelerator. A dynamic, multi-mode power management unit. The ARM926EJ processor, a powerful industry-standard CPU with Java acceleration. On-chip ROM and SRAM memory devices, including a 3-Mbit frame buffer. Security framework for enhanced mobile security, including stronger DRM. Multichannel DMA controller for efficient data transfer without CPU intervention. A multi-layer AMBA crossbar interconnect for optimized data transfers between the CPU, accelerators, memory devices and peripherals. Hardware semaphores for flexible inter-process management. A wide range of peripheral interfaces (GPIO, USB-OTG high speed, UART, IC, FIrDA, SD/SDIO/high-speed MMC/Memory Stick Pro, fast serial ports, TV output, color LCD and camera interfaces, scroll-key encoder, key-pad scanner). Direct support for high-level operating system such as SymbianTM, Linux and WinCE(R) operating systems (OSs). 4/8 STN8815 Low power consumption Low power consumption The new multimedia functionality of mobile products brings with it an increase in power consumption that is outpacing advances in battery technology. The STN8815 chip saves on power by avoiding the need for high clock speeds wherever possible, but its extremely low power consumption results from a systematic effort at all design levels to reduce power requirements. These include: The use of smart accelerators and distributed processing to off load from the CPU, Efficient code execution by means of innovative algorithms, energy-efficient instruction set architectures and Java acceleration, The efficient use of bandwidth for on-chip data transport, achieved by data compression, buffering and image scaling, Aggressive power management which includes turning off inactive parts of the chip and keeping the CPU in power-saving modes as much as possible. Open platform strategy STMicroelectronics is a founding member of the MIPITM Alliance working towards mobile software and hardware interface standards. Our open platform strategy provides manufacturers with roadmap flexibility, allowing them to avoid becoming locked into a proprietary CPU architecture or vendor technology. This approach is facilitated by the following design points. The STN8815 employs the third-party ARM(R) processor which is the standard CPU for mobile devices, with industry-wide application support. Open, standard APIs are provided for the development of application code on a level which is abstracted from the physical hardware. This allows the development of multimedia plug-ins that are portable between products and which can be reused on future products without modification. The STN8815 facilitates best-in-class algorithm development on its smart accelerators. The STN8815 is provided with development kits and tools that speed-up the integration of new operating systems, middleware, and signal processing algorithms. 5/8 Stacked memory options STN8815 Stacked memory options The STN8815S12 and STN8815S22 build on the STN8815 by stacking their respective amounts of both SDRAM and Flash memories in pin-compatible packages, a technology that STMicroelectronics has mastered for commercial use. In addition to saving space, the footprint of the stacked chips is the same as that for the STN8815, a critical factor for today's compact clamshell designs. These stacked versions give manufacturers unprecedented flexibility on the production line. The stacked versions promise lower product costs, added system security, faster data throughput, and future performance enhancements. 6/8 STN8815 Revision history Revision history Table 1.
