    Hi, I'm working on a low latency display project. Using PAL and the basic requirement is the low latency less than 70ms between capture and display. Could DM365 or any other DSPs meet this requirement? I feel wired after searching lots of informations. Many thanks. Zhu

    Tom Morrison
    Is this still the case? The latest points to just the dm3730 (or the OMAPL138)... Have they stopped development on DM365/DM368 DVSDK? This would be SO unfortunate! ?
