Leonard- Signalogic DirectDSP software supports MATLAB and Visual Studio communication with EVM563xx boards using a parallel port interface (small hardware adapter PCB). COFF download, processor/board control, symbol address lookup and read/write, bulk memory transfers, buffer ready callbacks, it's all there. Used to be a hot product in 1998-1999 :-) If someone is interested in taking the driver source code (includes both host side piece and DSP side piece) and modifying to support 568xx series EVM boards, we might be willing to provide guidance and advice. One key would be whether the 568xx devices contain an HPIO8 or very similar host interface.

Elevich" <> To: "'li_xinming'" <>,<> The following FAQ (DSP-14254) from our website may help you, in particular try the exercises that it talks about: Problem: How is Matlab supported by 56800 development tools? Solution: Matlab is not directly supported by our development tools, but you can use Matlab to generate inputs, which are readable by the EVM using SDK's File I/O. The results of processing these inputs can be uploaded from the EVM back to your PC using File I/O. Matlab can then process the outputs and compare them with predicted results. For more details on SDK's File I/O see Section 6.2 in the SDK Targeting manual belonging to your EVM. Examples of using File I/O and Matlab are available for 56F805, 56F807, and 56F826 EVMs. Download the 56800 FIR Lab SEA.exe (http://e-www.motorola.com/support/technial/faq/DSP/faq14254/FAQ_14254_FIR_Lab_S\ EA_V1.exe )or 56800 IIR Lab SEA.exe (http://e-www.motorola.com/support/technial/faq/DSP/faq14254/FAQ_14254_IIR_Lab_S\ EA_V1.exe ) and install it at the root of your Drive D:, then set the default directory in Matlab to D:\FIR_Lab\Matlab or D:\IIR_Lab\Matlab. In this directory you will find the Matlab script FilterLabScript.m which you can run from Matlab. Follow the prompts in Matlab. Leonard N.

Next, I have to process these data by MatLab Wavelet Toolbox. The problem is I cannot load data into MatLab. Does anyone have experience to handle the problem? Thanks for help in advance. David |
