scan-based emulation

TMS320x2xx

devices

incorporate

scan-based

emulation

logic

for

code-development

and

hardware-development support. Scan-based emulation allows the emulator to control the processor in the

system without the use of intrusive cables to the full pinout of the device. The scan-based emulator

communicates with the ’x2xx by way of the IEEE 1149.1-compatible (JTAG) interface. The ’C242 DSP, like the

TMS320F206, TMS320C203, TMS320LC203, and TMS320F243/241, does not include boundary scan. The

scan chain of these devices is useful for emulation function only.

development support

Texas Instruments offers an extensive line of development tools for the ’x24x generation of DSPs, including tools

to evaluate the performance of the processors, generate code, develop algorithm implementations, and fully

integrate and debug software and hardware modules.

The following products support development of ’x24x-based applications:

Software Development Tools:

Assembler/linker

Simulator

Optimizing ANSI C compiler

Application algorithms

C/Assembly debugger and code profiler

Hardware Development Tools:

Emulator XDS510 (supports ’x24x multiprocessor system debug)

The

TMS320 DSP Development Support Reference Guide (literature number SPRU011) contains information

about development support products for all TMS320 family member devices, including documentation. Refer

to this document for further information about TMS320 documentation or any other TMS320 support products

from Texas Instruments. There is also an additional document, the

TMS320 Third-Party Support Reference

Guide (literature number SPRU052), which contains information about TMS320-related products from other

companies in the industry. To receive copies of TMS320 literature, contact the Literature Response Center at

800/477-8924.

See Table 12 and Table 13 for complete listings of development support tools for the ’x24x. For information on

pricing and availability, contact the nearest TI field sales office or authorized distributor.
