launched the DM355 at the IBC broadcasters convention this week in London. It combines a 216MHz or 270MHz ARM9 core with a 640MHz DSP (digital signal processor) core. TI is currently sampling the chip as part of a DM355 DVEVM evaluation module. The module comes with a JPEG/MPEG-4 coprocessor and high-definition video-processing core implemented in microcode on the chip's DSP.
Signum says its JTAGjet-355 is compatible with TI's currently shipping IDE (integrated development environment) for DSP programming, Code Composer Studio Platinum 3.3. The emulator also supports "most major ARM debuggers," Signum said, specifically citing Windows CE Platform Builder and Linux GDB (GNU debugger). Additionally, the emulator is said to offer initialization macros and "simple flash programming and recovery" for TI's DVEVM evaluation module.
Additional touted features include:
- High-speed (480 Mbps) USB 2.0 interface
- Supports NOR and NAND flash programming
- Support for other RTOSes available
John Dixon, marketing manager for TI's DaVinci line, stated, "The emulator will allow developers to take advantage of the tools and support included in TI's DaVinci technology portfolio."
AvailabilityThe JTAGjet-355 emulator is available now. The "basic version" includes drivers for development teams using embedded Linux and GNU software and debug tools (a Linux BSP for the DM355's ARM core is included), Signum said. Windows CE Platform Builder support is an optional extra, as is support for CodeComposer Studio. Also available is Signum Systems's flagship Chameleon Debugger for ARM with embedded trace (ETB or ETM) support, drivers for eSOL RTOS and the eBinder debugger suite, and RDI drivers for 3rd party ARM debuggers.
In addition to TI's DM355, the emulator is said to support "all TI DaVinci technology and OMAP devices."
