The reference guides describe in detail the TMS320C55x

 DSP products currently available and the

hardware and software applications, including algorithms, for fixed-point TMS320 DSP family of devices.

A series of DSP textbooks is published by Prentice-Hall and John Wiley & Sons to support digital signal

processing research and education. The TMS320 DSP newsletter, Details on Signal Processing, is published

quarterly and distributed to update TMS320 DSP customers on product information.

Information regarding TI DSP products is also available on the Worldwide Web at http://www.ti.com uniform

Device and Development-Support Tool Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP

devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS

(e.g., TMS320VC5501). Texas Instruments recommends two of three possible prefix designators for its

support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from

engineering prototypes (TMX / TMDX) through fully qualified production devices/tools (TMS / TMDS).

Device development evolutionary flow:

TMX

Experimental device that is not necessarily representative of the final device’s electrical specifications

TMP

Final silicon die that conforms to the device’s electrical specifications but has not completed quality

and reliability verification

TMS

Fully qualified production device

Support tool development evolutionary flow:

TMDX Development-support product that has not yet completed Texas Instruments internal qualification

testing.

TMDS Fully qualified development-support product

TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer:

“Developmental product is intended for internal evaluation purposes.”

TMS devices and TMDS development-support tools have been characterized fully, and the quality and

reliability of the device have been demonstrated fully. TI’s standard warranty applies.

Predictions show that prototype devices ( TMX or TMP) have a greater failure rate than the standard

production devices. Texas Instruments recommends that these devices not be used in any production system

because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.
