When OMAP3 came out, the only compilers for C6000 were expensive, closed-source compilers. Now, there is support in mainline GCC for C6000. As the BeagleBoard.org community, we have to work together to enable use of the DSPs if they are of interest to the community---there aren't any barriers in our way. > > 09 Ноя 2014 г. 1:21 пользователь "John Syn" <[email protected]> написал: > >> >> From: sixvolts <[email protected]> >> Reply-To: "[email protected]" <[email protected]> >> Date: Saturday, November 8, 2014 at 8:31 AM >> To: "[email protected]" <[email protected]> >> Subject: [beagleboard] Re: BeagleBoard-X15 - seriously? :) >> >> Any ideas how this compares to the wandboard quad? 4x Cortex-A9 vs 2x >> Cortex-A15? >> >> According to this article: >> >> http://www.arm.com/products/processors/cortex-a/cortex-a15.php >> >> Cortex-A15 performance is double that of Cortex-A9.
