TMS320C8x Simulator

The Simulator uses the standard TMS320 Debugger Interface. The Simulator can be used to benchmark and to evaluate the C8x or to assist in code development when a target system is not available.

The C8x Simulator is a software program that uses the host processor (PC or workstation) to simulate instruction- and C-level operation of the C8x DSP. It essentially provides XDS510 software debug capability for a C80 or C82 plus external memory without the DSP hardware. Since the host is used to simulate the C8x, a program will run more slowly with a Simulator than with an SDB or XDS510.

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.

Simulate external interrupts.

Monitor the opcode and address at each phase of the pipeline with 8 pseudoregisters.

Parallel-Processors can share common breakpoints, which is not possible when using the actual hardware C8x.
