Key benefits

The STn8815 brings the following key benefits to mobile manufacturers and consumers:

●

Unsurpassed audio, video and imaging quality,

●

Ultra-low power consumption for longer battery operation,

●

Easier application development for shorter time-to-market,

●

Scalability for multiple market segments and future multimedia applications.

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, I²C, 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 Symbian™, Linux and WinCE®

operating systems (OSs).
