ARM yesterday made its move on the digital audio market with the launch of software designed to play back MP3 and Dolby Digital files on a standard ARM CPU. The plan is to promote ARM processors and the new software hardwired into ROM chips as a low-cost alternative to ASIC-based decoders. The software was developed with Cirrus Logic, which is building it into its own single-chip digital audio decoder, the EP7209, based on an ARM core. ®
