Texas Instruments (TI) has published an 18-minute videocast about programming its DaVinci RISC/DSP chips using Green Hills Software's (GHS) “Multi” IDE (integrated development environment). Used with a hardware JTAG probe, Multi permits simultaneous OS-aware debugging of Linux and DSP BIOS executives running on the DaVinci chips, GHS says.

In addition to Linux, Multi also supports GHS's proprietary RTOSes, such as Integrity, the presentation notes.

TI's DaVinci chips wed its TMS320C64x+ DSP cores with ARM926 applications processors. They target digital video processing applications, such as portable multimedia players (PMPs) and digital video recorders (DVRs), and are distributed with a MontaVista Linux OS, according to Greg Mar, a TI product manager who takes part in the persentation.

According to Mar, TI customers have long asked for off-the-shelf tools supporting simultaneous heterogeneous DaVinci debugging. Joe Fabbre, with GHS's business development team, says Multi can integrate with TI's Code Composer Studio, for DSP executive debugging. And, it can be used to program and debug Linux applications and kernel drivers, Fabbre says.

GHS has earned a reputation during the last several years as a harsh Linux detractor, thanks to opinionated press releases issued by CEO Dan O'Dowd. One release predicted the death of the Linux tools market, while another called Linux a national security threat.
