6 Device and Documentation Support

6.1 Device Support

6.1.1 Development Support

TI offers an extensive line of development tools for the OMAP-L13x platform, including tools to evaluate the performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug software and hardware modules. The tool's support documentation is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE).

The following products support development of OMAP-L13x applications:

Software Development Tools:

Code Composer Studio™ Integrated Development Environment (IDE): including Editor

C/C++/Assembly Code Generation, and Debug plus additional development tools

Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target software needed to support any application.

Hardware Development Tools:

Extended Development System (XDS™) Emulator

For a complete listing of development-support tools for OMAP-L13x, visit the Texas Instruments web site on the Worldwide Web at www.ti.com uniform resource locator (URL). For information on pricing and availability, contact the nearest TI field sales office or authorized distributor.

6.1.2 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: X, P, or NULL (e.g., XOMAPL137). 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 (X/TMDX) through fully qualified production devices/tools (NULL/TMDS).

Device development evolutionary flow:

    X Experimental device that is not necessarily representative of the final device's electrical specifications.
    P Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification.
    NULL 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.

X and P devices and TMDX development-support tools are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes."

NULL 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 (X or P) 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.

TI nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, ZKB), the temperature range (for example, "Blank" is the commercial temperature range), and the device speed range in megahertz (for example, "Blank" is the default).

Figure 6-1 provides a legend for reading the complete device name for any OMAPL13x member.

6.2 Documentation Support

The following documents describe the OMAP-L13x Low-power applications processor. Copies of these documents are available on the Internet at www.ti.com. Tip: Enter the literature number in the search box provided at www.ti.com.

    DSP Reference Guides
    SPRUFE8 TMS320C674x DSP CPU and Instruction Set Reference Guide. Describes the CPU architecture, pipeline, instruction set, and interrupts for the TMS320C674x digital signal processors (DSPs). The C674x DSP is an enhancement of the C64x+ and C67x+ DSPs with added functionality and an expanded instruction set.
    SPRUFK5  TMS320C674x DSP Megamodule Reference Guide. Describes the TMS320C674x digital signal processor (DSP) megamodule. Included is a discussion on the internal direct memory access (IDMA) controller, the interrupt controller, the power-down controller, memory protection, bandwidth management, and the memory and cache.
    SPRUH92OMAP-L1x DSP+ARM Processor Technical Reference Manual. Describes the System-on-Chip (SoC) and each peripheral in the device.
    User's Guides
    SPRU186 TMS320C6000 Assembly Language Tools User's Guide.Describes the assembly language tools (assembler, linker, and other tools used to develop assembly language code), assembler directives, macros, common object file format, and symbolic debugging directives for the TMS320C6000 platform of devices (including the C64x+, C67x+, and C674x generations).
    SPRU187 TMS320C6000 Optimizing Compiler User's Guide. Describes the TMS320C6000 C compiler and the assembly optimizer. This C compiler accepts ANSI standard C source code and produces assembly language source code for the TMS320C6000 platform of devices (including the C64x+, C67x+, and C674x generations). The assembly optimizer helps you optimize your assembly code.
    SPRUG82 TMS320C674x DSP Cache User's Guide. Explains the fundamentals of memory caches and describes how the two-level cache-based internal memory architecture in the TMS320C674x digital signal processor (DSP) can be efficiently used in DSP applications. Shows how to maintain coherence with external memory, how to use DMA to reduce memory latencies, and how to optimize your code to improve cache efficiency. The internal memory architecture in the C674x DSP is organized in a two-level hierarchy consisting of a dedicated program cache (L1P) and a dedicated data cache (L1D) on the first level. Accesses by the CPU to the these first level caches can complete without CPU pipeline stalls. If the data requested by the CPU is not contained in cache, it is fetched from the next lower memory level, L2 or external memory.

6.5 Electrostatic Discharge Caution


This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
