ST Microelectronics has unveiled first details of a new family of multimedia application processor chips that will enable portable terminals to play music, take pictures, record video, and host two-way visual communication in realtime. These processors are aimed at 2,5/3G mobile phones, PDAs and other portable wireless products with multimedia capability, as well as for automotive multimedia. Called Nomadik, the multimedia application processor family, which offers ultra-low power consumption, are based on the combination of an ARM926EJ-S core together with programmable 'smart accelerators' that operate independently and concurrently to handle the key video and audio coding functions, including pre/post-processing. The distributed processing approach simplifies software development since developers need only write code for the ARM core. In addition, since multimedia functions are not typically executed on the main processor core, there is more headroom for adding new software applications in the future.
