Tremor

Texas Instruments TMS320C55x DSP Family

Download the generic lowmem source using Subversion. This is probably the version you want to start working with for a DSP.

svn co http://svn.xiph.org/branches/lowmem-branch/Tremor/

Required / Suggested Changes to the code as downloaded:

• Roland Wintersteller's various fixes

See the mailing list entry

• Johannes Sandvall's performance improvements

See the mailing list entry or just download

• alloca removal

The TI compiler does not support this.

• misc compiler warning fixes
• hooks to TI DSPLIB functions cfft3216_NOSCALE and cbrev32

These are part of the TI DSPLIB which can be downloaded from the TI website.

• 64-bit math functions
• converting all ints assumed to be 32 bits to ogg_int32_t
