PlayMedia Tunes AMP for StrongARM and XScaleBy PlayMedia Systems, Inc., has tuned its AMP MP3 playback technology for the Intel StrongARM processor and Intel XScale Microarchitecture. PlayMedia's audiovisual framework, NewArk, now runs embedded applications. The NewArk Audiovisual Framework enables consumer electronics' audiovisual-related tasks, including MP3 encoding and decoding, video encoding and decoding, and special audio effects, such as cross-fades and echo. PlayMedia's AMP decoder is available both as a NewArk module and as a stand-alone application. Additionally, NewArk supports digital rights management technologies from PlayMedia and third-party providers. Previously, MP3 playback on portable devices required a costly and inflexible dual-chip design; a dedicated digital signal processor was needed to handle decoding functions, while a main processor executed other playback tasks. The performance and power consumption of the Intel XScale Microarchitecture enables NewArk and AMP to perform both of these tasks on a single processor. This reduces the amount of battery power required. Developers can also save on RAM for decoding tasks, reducing costs with this single-chip design. PlayMedia's NewArk Audiovisual Framework consists of a base structure and numerous modules, or nodes. Each node handles a dedicated audiovisual processing tasks. By grouping different nodes together, developers can create unique audiovisual effects, maintain file security, and establish rights management methods. PlayMedia offers a library of pre-programmed nodes that perform data input and output, data processing, special effects, and multi-stream functions on the NewArk framework. The input and output nodes perform tasks such as automatically determining an audio file format and enabling playback to a sound device. PlayMedia's processing and special-effects nodes enable advanced playback functions, such as automatic gain control, cross-fading, audio equalization, reverb, and tempo control. NewArk's multi-stream modules can enable multiple audiovisual tracks to be mixed or split to create complex audiovisual configurations. PlayMedia also provides nodes for its own digital rights management and file security technologies. Customized nodes can also be created to perform other specific audiovisual-related tasks or to support third-party technologies. The NewArk framework uses a low memory footprint and single-threaded multi-stream processing, which reduces system resource consumption and allows it to run on simpler system architectures. In addition, the NewArk kernel requires only a single string of execution commands to perform processing and control functions. PlayMedia Systems currently offers or has in development versions of the NewArk audiovisual framework for the Microsoft Windows, Symbian, Unix/Linux, Palm OS, and Mac operating systems. PlayMedia Systems' AMP technology supports the MP3 audio encoding standard. AMP has enabled millions of people to listen to digital music through players such as AOL's Winamp, Napster, and Subband's MacAmp. AMP is also used in other diverse applications such as CD-ROMs, online games, music education applications, digital music jukeboxes, and music playback in retail establishments. PlayMedia's AMP runs on major wireless and handheld operating systems such as Microsoft's Pocket PC, Symbian OS, Unix/Linux, and Palm OS. AMP is also supported on common mobile telephony systems, including GSM, GPRS, CDMA, CDPD, and WCDMA. Link: |
