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

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.,
TMS
320C6412GDK600). 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.
