This kind-of makes me think of TI's OMAP soc devices that have one (or more) cortex-A CPUs + an additional cortex-M for "slow stuff". Just wondering, will it actually be able to access these additional processors? I have a pandaboard which is OMAP4430 based. That chip also has an additional DSP core and a GPU. However, I never really found a good document that describes how to actually use the. I read that the DSP core had to be addresses via some special API, that was about it. So, will we be able to use these additional cores? I would be interested to know how coding this kind of enviroment really is done. 73 Kristoff - ON1ARF ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
