New decoding middleware for the SH-Mobile application processor supports aacPlus audio coding technology. The middleware simplifies the development of multimedia applications, such as high quality music distribution services, for next-generation mobile phones that use aacPlus and the SH-Mobile device.
It also includes optimised algorithms that allow the device's on-chip DSP to be used to its full potential, enabling high-performance applications to be developed.
aacPlus is a highly efficient coding technology that combines MPEG AAC (Advanced Audio Coding) and the SBR (spectral band replication) technology developed by Coding Technologies.
aacPlus offers twice the coding efficiency of the conventional MPEG-2 AAC LC method, enabling data of the same quality to be achieved at approximately half the data transfer speed.

Microcontroller allows low-cost smart cards
Renesas Technology Europe's AE41R enables low-cost implementation of a contactless system compatible smart card offering a high level of user convenience and simple operator maintenance
This makes it possible to achieve higher sound quality at limited data transfer speeds on communication lines and to halve the data transfer speed required to maintain the same sound quality as before.
The aacPlus Decoding Middleware complies with the MPEG-4 High Efficiency AAC Profile standard and implements SBR technology.
The middleware provides a C-language function interface that, when incorporated into a program, simplifies the development of aacPlus applications and improves development efficiency.
The interface is equivalent to Renesas Technology's current MP3 and MPEG-4 AAC middleware, facilitating the development of multiple-codec type applications that allow switching between different audio coding methods.
With applications that use aacPlus for video distribution services including audio, the aacPlus Decoding Middleware can be easily combined with Renesas Technology's MPEG-4, H.264, or similar moving image middleware.
This provides development solutions for a wide range of multimedia applications.
