[LAD] supporting a dedicated DSP chip with ALSA

Hi All, i'm seeking an advise on the preferred way to support a dedicated DSP chip under ALSA. The system is an embedded system constructed on a dual core chip - one core is ARM vanlia and the other is a dedicated DSP core. The DSP core is capable of both playing both encoded streams (mp3, wma, various voice coders) and of course PCM streams. the codec (a2d, d2a) are connected to DSP. I looking for an elegant design to hide the DSP under the ALSA sysem and I have several ideas and would like to get your advise: 1. use LADSPA to make the DSP look as a plug-in for both control and data - what I don't know is if LADSPA forces me to return data to the ALSA for sending it to the kernel drivers 2. use the LADSPA to make the DSP control only and make another kernel driver for the audio data pass - is it possible? There can be a sync problem between the commands and the time the data will arrive? Will this support JACKD ? I'm open to other suggestions as well, Thanks in advance Ziv ______________________________________________________________________ DSP Group, Inc. automatically scans all emails and attachments using MessageLabs Email Security System. _____________________________________________________________________
