OMAP L1. 38 Software Design Guide Texas Instruments Wiki. Introduction. The purpose of this software design guide is to walk developers through the various stages of designing software for TIs C6 Integra ARM DSP devices as well as the C6. DSPs. The guide follows the structure shown in the Software Design Timeline below. Each design stage in the Timeline links to a collection of useful documentation, application notes, and design recommendations pertaining to that stage. Using this Guide, software designers can efficiently locate a resource or collection of resources they need at each stage in the software development process. Note This guide is not as a replacement for information specified in the data manual nor is it designed as a replacement for information on TI. Software Design Timeline Determine Top Level Software Hierarchy. Real Time Operating System RTOSReal Time Operating Systems are specifically designed to appropriately schedule signals to be handled with minimal latency at the specific time when the the signal occurs. RTOS such as TIs DSPBIOS later renamed SYSBIOS to reflect multi core ARM lt DSP interactions is one such example of a RTOS that has been specifically designed and successfully used on multiple C6x DSPs for years. The below links will direct you to more information about the DSPBIOS and SYSBIOS which are the officially supported RTOSs of TI, and are available free of charge. This converter enables the addition of Com Ports to Windows Computers having USB capability. Global and Group Priority The application software is in control of when interrupts are reenabled within a interrupt service routine. This might be at the beginning. Note DSPBIOS is the precursor to SYSBIOS, although both are supported. Those who are not as familiar with RTOS will benefit with starting with DSPBIOS as it has a greater number of drivers for new and legacy devices. TI DSPBIOS for C6. DSPTI SYSBIOS for C6. DSPIn additional to DSPBIOS and SYSBIOS there are additional available RTOSs that can be run on C6 IntegraC6. Devices, each with it own benefits, however it should be noted that these RTOSs are not always free of charge, nor are they directly supported by TI.

Generic Operating System OSDeveloping on a generic operating system OS can jump start your development by providing a predefined code structure and typically existent peripheral drivers which allow you to focus directly on your end application development code. While this may sound advantageous, its important to understand that the benefits that one gains with a traditional operating system can quickly be out shadowed by non optimized code that can quickly consume a lot of unnecessary processing power andor available on chip system memory resulting in a higher overall system cost. The following matrix lists Generic Operating Systems are available for C6 IntegraC6. Devices. No Operating System Software development on a device without the use of any operating system is typically done when a very minimal code footprint is needed, or an operating system may add unnecessary complexity that is not needed. Development with no operating systems are typically discouraged because it requires an application to rely solely on interrupts for scheduling. While this approach does work, it quickly becomes a heavy burden on the developer to appropriate structure code to manage all events, when the code will need to manage for future undefined programs. As the application scales to meet additional demands of your customers, additional demands of not using an operating system may sideline you into re using your your differentiating your products from those your competitors provide.

DSP Software Libraries Download, Purchase, or Install Appropriate IDE Tool ChainsOnce you have decided on the appropriate software hierarchy that is appropriate for your design, the next step is to pick to tool chain that will quickly assist you in developing your end applications. Integrated Development Environments IDEs provide a software developer a base set of software which allows a programmer to get started writing and testing code. IDEs typically include a Text Editor, The software tool chain, and a debugging environment all in a single application that typically runs from a host PC. A tool chain typically consists of at least one C compiler, an Assembler, and a Linker. The tool chain is CPU architecture dependent, so the right tool chain is dependent on the CPU of choice as well as any additional constraints imposed by the host operating system. C6x Integra Devices offer wealth of various tools chains and IDEs due to the integration of both the ARM CPU core and the C6. DSP core, both of which have a different instruction set architecture ISA. TI provides both an IDE as well as a tool chain for development on C6x Integra devices. Scale Card Model Ship.

TI offers wealth of additional Application Programming Interfaces APIs for the C6 Integra devices which serve to abstract programming each register at the bit level as well as to provide a well defined method to program the C6 Integra devices. Additionally, there are various software packages available for download which can help you jump start your software development based upon your preferences. Rock Tour Game.

Hardware Development Platforms are designed, developed, and tested by 3rd Party Design Houses in order to provide the software architect team with the ability to develop their code in parallel with the hardware design of the Printed Circuit Board PCB. Hardware Development platforms are preferable vs simulators because they actually reflect how the device will behave in the end product and take into account system latencies for cache misses and off chip memory accesses. Texas Instruments provides a variety of reference designs for JTAG Emulators called the XDS series. These emulators come in various different classes based upon the desired level of support.
