firewort writes "Neuros, makers of the Neuros Audio mp3 and ogg player and the new OSD, have negotiated the open source release of a DSP toolchain from Texas Instruments. "The toolchain includes a compiler, optimizer, assembler, and linker. The OSD is based on a TI DM320, and features a C54x DSP clocked at 120MHz. The C54x is also found in DM270 parts. As for other Linux devices? Born said, "There are Cowon and other devices that use the c54x,""so this opens up a DSP to developers that was formerly only available through a closed-source license and at a cost of $3000 for a developer board to work upon. The OSD has been endorsed by no less than Linus Torvalds."
