Hi, I am new to the DSP world. I need to develop an application on a board that interfaces Microprocessor to DSP. I am basically working on processing Audio signals from Microprocessor with DSP.I am just curious if I can pick an off-the-shelf board(SHARC Processor) running linux preferably that I can use for development. Thanks, Raghu

Hello All, Is there a way to tell what the initial value of a global variable has been set to from the ldr or dxe file? I am trying use a global variable for version control and would like to see how access the global variable without having to load the code into H/W or simulator. Thanks. Regards. BSA

Hi to All of you. I am currently interfacing a master slave configuration of the AD1819A to the ADSP-21065L SHARC processor. I was wondering if any one of you guys know how to daisy chain these codecs. My master is working well, but my slave codec doesn't seem to respond to sti

I'm using the AD14060 Quad SHARC (four ADSP-21060s). The DSP IDs read from the SYSYTAT registers are reversed from what is expected; In VisualDSP++ 2.0, DSP_A reports an ID of 4, DSP_B's ID is 3, DSP_C's ID is 2 and DSP_D's ID is 1. This leads to the LDF file having the incorrect MPMEMORY

Hi all, We recently started to work with the Ez-kit 21369 evaluation board from ADI. Compiling, Flashing and running algorithms works like a charme. BUT we suddenly destroyed 2 boards. And thus bought an antistatic mat with antistatic wrist band. Despite of lots of precaution playing with the board we still destroyed 3 of them after while... It seems that the processor still r...
