OVERVIEW

JDSnet is a real-time transparent in-circuit emulator for the TMS320 DSP family of microprocessors, based on the MPSD debug port. The emulator connects to a standard parallel port (LPT1-LPT4) of a desktop or notebook PC.

JDSnet may be ordered with Code Composer or with Chameleon Debugger designed to handle multi-core IC’s and systems running multiple CPUs. Chameleon Debugger for the TMS320C3x family provides a consistent GUI user interface to an embedded project at all stages on the development and production cycles. Being a 32-bit multi-threaded Windows application, Chameleon supports multiple CPUs in a single GUI debugging environment. There is no need to switch from screen to screen because Chameleon displays information on all active CPU on the same screen making the debugging process easier. Regardless of the number of CPUs being debugged, Chameleon offers the latest debugging features such as fly-over variable watch, drag and drop variables, Virtual I/O, complex variable implode/explode, script language for automatic testing, symbol browsing, and more. Step-into, Step-out and Step-over modes are supported for both C and assembly levels. Our unique graphical interface for complex events is quick, intuitive and incredibly easy to use. This debugger is an ideal and indispensable tool for developing embedded systems based on Texas Instruments TMSC3x DSPs.

Just a simple click on Chameleon's EVT icon gives the user access to hardware breakpoints implemented in CPU cores. (Different cores may have different sets of on-chip breakpoints. Intuitive user interface allows you to visually define break conditions on various program execution cycles and memory access cycles. Break condition can be combined using logical operators or may be generated after certain number of events.
