DESCRIPTION
The C3x Simulator is a software program that uses the host processor and memory to perform instruction- and C-level simulation of the C3x DSP. It uses object code produced by the macro assembler/linker or ANSI C compiler and the standard TMS320C3x Debugger Interface. The simulator provides XDS510 software debug capability for a C30 or C31 plus external memory without the DSP hardware.

The simulator provides cost-effective application development and program verification in non-real-time. Each of the simulator's software programs simulates C3x operation and allows monitoring of the state of the processor. Simulation speed is typically on the order of hundreds of instructions per second on a PC.


 
FEATURES
Key features of the C3x simulator -- and common to all TMS320 software simulators -- include:
  • Execution of user-oriented DSP programs on a host computer
  • Modification and inspection of registers
  • Data and program memory modification and display:
    • Modification of an entire block at any time
    • Initialization of memory before a program is loaded
  • Simulation of peripherals, caches, and pipelined timings
  • Extraction of instruction cycle timing for device performance analysis
  • Programmable breakpoints on:
    • Instruction acquisition
    • Memory reads and writes(data or program)
    • Data patterns on the data bus or the program bus
    • Error conditions
  • Trace on:
    • Accumulator
    • Program counter
    • Auxiliary registers
  • Single-stepping of instructions

The Simulator offers the following additional features to the TMS320 Debugger Interface :

  • Memory-mapped I/O can be connected to a host file to simulate I/O such as synchronous serial port I/O.
  • The simulator can simulate external interrupts.
  • It can monitor the opcode and address at each phase of the pipeline with 8 pseudoregisters.

TMS320C3x Debugger Interface

The TMS320 Debugger Interface is used with all TMS320 Simulator, Emulator, and EVM products including the C3x Simulator, C3x XDS510/XDS510WS Emulator Debugger and the C3x EVM Debugger.

Texas Instruments

The Debugger allows you to run and halt the processor; view and modify registers, memory values and C variables; and view disassembly and C source. Debugger features include:

¡@

  • Ability to start and halt the C3x with single-step (step-into), step-over (next), run, and halt commands.
  • A friendly window-, mouse-, and menu-oriented user interface that reduces learning time and eliminates the need to memorize complex commands.
  • Support for debugging in C, assembly language, or both.
  • Profiling capabilities that show where to focus development time by identifying time-consuming sections of the program.
  • CPU window that displays the values of the DSP registers.
  • Disassembly window that displays the address, opcode and disassembly of the program and highlights the current instruction.
  • C source window that displays the C code and highlights the current line.
  • Memory window that displays the values of a block of memory in any format specified.
  • Watch window that displays the values of variables in their native C format (float, int, char, enum or pointer) or lets you choose a different format.
  • Display windows that display the values of arrays and structures.
  • Command window that can be used to enter commands and view the response to commands.
  • Pull-down menus and function keys that provide quick access to frequently-used commands.
  • Ability to point the mouse, click and type in order to change the value of data in any window.
  • Screen update whenever the C3x halts.
  • Support for a powerful command set
  • Configurable screen colors, window sizes and window positions.
  • Ability to set and clear software breakpoints in the disassembly or C source windows with a mouse click.
