One line from the 6/28/99 press release about Texas Instruments, Liquid Audio, Fraunhofer and SanDisk teaming to offer a new SDMI player design is a little disturbing to the idea of MicroOS as necessary to the design: "TI, the world leader in DSP, will provide DSPs and a complete library of software decoders" I spent a few moments on the TI website looking for some answers to the MicroOS question. It was pretty intimidating. Texas Instruments has hundreds of technical papers discussing the application of digital signal processors in a wide variety of devices. Their product line is huge and the specific DSP to be used for music players is just one of dozens currently offered. If you want to venture through the site, start here: www-d.connect.ti.com This is the Third Party Applications Resource Center. I followed leads through Audio applications, including MPEG functions, but found nothing relevant to our discussion.

Dave, On reflection, you are probably right about the MicroOS being stored in the flash memory, rather than embedded in the DSP. This would make more sense for mass production and would reduce the cost of the DSP. Perhaps another avenue for research would be to contact SanDisk and ask them if MicoOS is necessary to the use of their flash memory chips when running multiple CODECs. My head hurts. I need to re-read Kerry's favorite quote. Jim

Think of it this way....conceptually speaking TI's DSP(think hardware) is to a micro OS(in this case EDIG), what the Intel Pentium series chips are to Microsoft's(or Linux or Apple's) operating system. A platform upon which software runs. As such it stands to reason that EDIG can have competitors, as long as they can figure a way to "scrunch down", or build, their OS to fit the constraints of TI's DSP's. And therein lies the rub for competitors, eh? Still, clearly(based on all the news of late) it's a free for all out there right now. Almost beta vs vhs raised up a quantum level. So let's see how it plays out... John~
