Crossware Coldfire Suite Builds Freescale's Trio MP3 Application.CAMBRIDGE, England -- Crossware (www.crossware.com), a leading embedded software Instructions that permanently reside in a ROM or flash memory chip. Embedded software may be immediately available to the CPU or, for faster execution, may be transferred to RAM first and then executed. tools developer, has released a new version of its ColdFire(R) Development Suite which is able to build the Trio MP3 application software developed by Freescale Semiconductor for use by its ColdFire customers. Based on the Flex real time operating system A master control program that can provide immediate response to input signals and transactions. See real time system and embedded Linux. , the Trio MP3 application runs on the ColdFire MCF5249 and SCF SCF Service Canadien des Forêts (Canadian Forest Service) SCF Stem Cell Factor SCF Scientific Committee on Food (European Commission) SCF Service Canadien de la Faune 5250 microprocessors. It includes not only an MP3 decoder and encoder but decoders for Microsoft Windows Media Audio (WMA (Windows Media Audio) An audio compression method from Microsoft. Known originally as MSAudio, this proprietary format competes with the MP3 and AAC methods. WMA encodes rapidly and is known to be especially effective at low bit rates. ), Advanced Audio Coding (audio) Advanced Audio Coding - (AAC) A successor to MP3, allowing lower bit rates and more stable quality. See MPEG-2 AAC Low Profile and MPEG-4 AAC Main Profile. (AAC (Advanced Audio Coding) An audio compression technology that is part of the MPEG-2 and MPEG-4 standards. AAC, especially MPEG-4 AAC, provides greater compression and better sound quality than MP3, which also came out of the MPEG standard. ), Ogg Vorbis and other format files. These files can optionally reside on a hard drive, CD drive or SD card. "In adding support for the Trio MP3 application, we are responding to the rapid growth of interest in compressed audio technology which looks set to extend well beyond the portable device and home entertainment environments into markets such as automotive," says Alan Harry of Crossware. "With the introduction of our new version of the ColdFire suite, users now have a choice of development environment for this increasingly popular and expanding application - and can take advantage of the enhancements to our Embedded Development Studio which will speed the whole development process." Freescale supplies its Trio MP3 application as source code and a set of precompiled libraries. A set of 'makefiles' is also supplied which are used to control the compiler, assembler and linker during the build process. However, an enhancement to the Crossware Embedded Development Studio enables these 'makefiles' to be used to automatically create the files necessary for the application to be built from within Crossware's user friendly GUI (Graphical User Interface) A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant advantages of a GUI vs. a character-based interface. development environment. For example, the user has simply to browse to the folder containing the master 'makefile' and the Embedded Development Studio will create the completely configured development Workspace in less than 30 seconds. The application can then be immediately built, downloaded and run on the target board. Flash videos illustrating the Workspace creation, build and download process are available on the Crossware web site at: http://www.crossware.com/mp3player.
