TMS320C5x XDS510/XDS510WS

TI provides C5x emulation systems for both PC and SPARC systems:

XDS510: a PC version consisting of a half-size AT board and a JTAG emulation cable.
XDS510WS: a SPARC version consisting of an external controller box, a SCSI cable, a power supply, power supply cable, and a JTAG emulation cable. The controller box connects to the SPARCstation via the SCSI cable.

The emulator enables the TMS320 Debugger Interface, which is sold separately, to control the C5x on the target board. This is done by interfacing the target system to the emulator via the JTAG emulation cable. The Debugger can then be used to verify the functionality of the C5x software and target hardware.

The emulators use scan-based emulation which is a nonintrusive approach to system emulation and debug. The emulator connects to a 14-pin header that must be designed into the target board. This header consists of a power signal, a clock signal, some ground signals and the 4 JTAG pins of the C5x.

The revisions in the emulators are determined by the letters on the chip: an A in 6.7, B is 7.2, C is 7.3.

Key features of the XDS510/XDS510WS include:

• Global run/stop/breakpoint of parallel-processing DSPs
• High-level language debugging interface
• Software breakpoint/trace on all program and data addresses
• Single-step execution
• Windowed user interface similar to that of the 'C4x simulator
• Loading/inspecting/modification of all registers and memory
• Benchmarking of execution time of clock cycles
