-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks -
We had some internal talk about how to go post GTA02 and Wolfgang wants us to make it external. We have a choice about basing on S3C2443 or S3C6400. A lot of the info is confidential but not these high level things which are public domain on Samsung's site. S3C2443 is an 130nm incremental improvement over the 2442 in GTA02 with 480Mbps USB Device (not OTG) and better clock scaling. It can accept x16 DDR memory. S3C6400 is 90nm and has 480Mbps USB2 OTG, 667MHz max clock, some 2D acceleration and can accept x32 DDR memory. http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=229&partnum=S3C6400 http://www.samsung.com/global/system/business/semiconductor/product/2007/8/21/661267ptb_s3c6400_rev15.pdf I like the 6400 better but information is a bit scarce right now and it can go either way. Some other concepts kicked around: - Merge the debug board function on to the phone, perhaps with internal micro USB used for debricking and hacking. No write-once memory. - Discard U-Boot, minimal bootloader direct to kernel - Focus on SD Card rootfs rather than internal memory - Add a small lowpower MPU like TI MPS430 to manage everything seamlessly when main CPU is down. Stuff like motion sensors, wake sources, battery management, maybe touchscreen, leds so there is an always-on "guiding hand" in the phone that is consistent and reliable To be clear though -- GTA02 is soon going to actually exist, and this is just future talk right now. But because of that, if you have any ideas about future arch, now is the time to throw them in and they will at least get the time of day. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFH4OqjOjLpvpq7dMoRAldNAJ4kDtEv4ktKAVdw9UlW1G9+fEUMvgCfdH1e s67SFaeGcz6TgckzPo1Q20g= =/oXX -----END PGP SIGNATURE-----
