Emulator

The JDSnet-TMS320 emulator uses the JTAG debug port for accurate breakpoint control and for accessing any on-chip registers and memory. It offers a complete debugging tool-set for the TMS320C2xx, 3x, 5x, and 54x families. With the 128- or 256-K optional trace buffer module, the emulator is capable of storing DSP's program and data flow information with a time stamp in real-time, while executing user applications. The acquired trace information is displayed in a trace window without the need for stopping the DSP. The trace window shows the program flow along with the corresponding C or assembler source code and a bus-cycle, accurate-time stamp. Any part of the trace may be exported to other applications for further analysis or graphing.

The emulator is equipped with a standard parallel port to connect to any desktop notebook or workstation PC. It can be connected directly to the thin (10Base2) or twisted-pair (10BaseT) TCP/IP network using the optional Ethernet port. To interface the trace with user's target application boards, it uses a small adapter pod. This universal pod accepts many different footprint adapters (QFP, TQFP, LQFP, PLCC) depending on the DSP's package. A separate cable is dedicated for the JTAG debug port, which allows access to the on-chip registers, breakpoints and internal or external memory.
