Question about TMS320C6748EVM

Other Parts Discussed in Thread: OMAP-L138

Hello ,

I need to run audio algorithm in realtime mode without OS.

The TMS320C6748EVM (http://www.ti.com/tool/tmdsevml138) is very high performance, but I don't know

It is easily possible to run without OS.  I just need audio input and output and control panel port to control audio volume etc.

Basically, It is possible to run without OS, but I am worry it has complex architecture, that's why not easily implement.

If anybody know this board, could you explain it is possible or not?  Can I get example code for non OS example?

I need uart and I2C for Control panel port in my PC.

Thanks in advance

    Hi,

         Yes, it is high performance device while talking about your application. For your application one core is sufficient, But this platform has two cores (ARM, DSP), refer this link http://www.ti.com/product/omap-l138 also to more about this.

         But for sure your application can be run on this.

         I doubt you will get non OS applications, i think you have to write your own, but there is SDK package available for this, which runs Linux on ARM & BIOS on DSP, this SDK has source code for huge set of applications like video playback, including the audio application you mention.

        Download this SDK from http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html

        You can get support for this SDK in this forum.

        UART is supported, I do not know what you mean by I2c to PC.

    Best Regards

    Thank you for your reply

    I want to communicate with my Windows 7 64bit using I2c port. I believe this EVM system may have some connectivity to my desktop computer.

    if I want to use code composer in non OS environment which one is better solution

    http://www.ti.com/tool/tmdsoskl137 and http://www.ti.com/tool/tmdsevml138.

    I am worry about L137's performance, that's why I am think about L138.

    Could you please comment about those architecture for algorithm development? 

    I need real time computing power and control port for GUI that's why I have mention about non OS environment.

    Best regards,

    Doug

    I found I2C connector pin L137 board schmatic,but I have no L138 board schematic. I believe L138 board also have I2C connector pin. Do you know where can I get L138 board schematic ?

    You can download the L138 board schematic from LogicPD website at http://www.logicpd.com/products/system-on-modules/zoom-omap-l138-evm, Click at "Documentation & download" link at the left side.
