Signum Ships JTAG Emulator For TI Chip With ARM Host Control

Signum Systems has started shipping a JTAG emulator for use with Texas Instruments Incorporated’s (TI) sub $10 DM355.

The DM355 processor consists of an integrated video processing subsystem, an MPEG-4-JPEG co-processor (MJCP), an ARM926EJ-S core and peripherals.

Signum Systems’ JTAGjet-355 emulator supports all TI DaVinci technology and OMAP^TM devices, but with its native eBinder^TM and Linux support, it is configured especially to fit the DM355 targeted development environments. The emulator comes with high-speed (480 Mbps) USB 2.0 interface to a Windows or Linux based host PC to allow fast code downloads, high-speed.

“Signum’s new JTAG emulator for DaVinci technology helps to further the development of next-generation, portable digital video devices,” said John Dixon, DaVinci marketing manager, Texas Instruments. “The emulator will not only enhance the DM355 development experience, it will allow developers to take advantage of the tools and support included in TI’s DaVinci technology portfolio, saving them months of development time.”

The JTAGjet emulator is compatible with TI’s Code Composer Studio^TM (CCStudio) Platinum, version 3.3 integrated development environment (IDE) as well as most major ARM debuggers, Linux GDB based ARM debuggers and Microsoft WinCE Platform Builder, the company said. It also fully supports the TI’s DM355 Digital Video Evaluation Module (DVEVM) with a board support package that includes native Linux connectivity, initialization macros and simple flash programming and recovery in case of accidental erasure. The emulator’s Embedded Trace Buffer (ETB) adds extra visibility into the executing code in real-time to allow tracing of the executing program and its variables.

For projects using non-Linux tools, JTAGjet can be ordered with Signum Systems’ flagship Chameleon Debugger for ARM with Embedded Trace (ETB or ETM) support, drivers for eSOL RTOS and eBinder debugger suite, support for CCStudio, RDI drivers for 3rd party ARM debuggers and WinCE Platform Builder support.

The JTAGjet toolset already supports other devices including ARM7, ARM9, ARM11, Cortex, OMAP and TMS320 DSPs to provide natural, non-intrusive methods to quickly locate and fix bugs in the embedded software or firmware.
