Your putting that info in an email was a good thing to do for the entire community, but one thing which kinda worries me for it's future implications is that all of the info about the Pandoras seems to come in little dribs and drabs like above. There doesn't seem to be any big spec sheet. Just means that getting all the specs seems to be a bit more difficult than I think it should be. >> These core's are then licensed to chip manufacturers for them to use. I love the fact that they're got that top quality 3D code for the TI 320 that's embedded, but it says that all the code is available via NDA. Sigh, I thought that all of that idiocy would be left behind for a project that advertised as open-source derived.

According to what I thought I read, the arm7 has changes from the arm5 it's derived from. Supposed to me 2-3 times more code-efficient? I hope I learn more before I get my toy. Do you have any idea what the FP environment is? softfp? > > DES -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkng5KcACgkQz62J6PPcoOkdxwCgn9T3AJIJqcEnz4j8bw13bP1G H9kAoJ7gxgcbKn/8dt4Qvi7sVUR3DjoP =z5C8 -----END PGP SIGNATURE-----
