Have you got any rough estimation about memory-MIPS requirements for the fixed point implementation? The target hardware will be a motorola style single MAC 16bit fixed point DSP. Is here any implementation of speex on DSP? Thanks G.

This was also our experience porting the Tremor vorbis decoder to a TI dsp. The vendor toolchain is useless; someone really...

Hi We just installed a W server 2008 server as antivirus server. As this server is heavily underused we created a share to backup files from other servers. This share is easily accessed from XP pro Pc's via \\ipadr\share and giving a user/password name on the W 2008 server. We then try to use it from an open suse 9.3 linux server via smbclient. smbclient //ipadr/share -U user%password

I noticed a little while back that Andrew@teledesign.co.uk posted he was going to port the speex onto a TI DSP. Any news on this or similar developements? --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in
