Hi, I am facing a problem for initializing the codec at variable sample rate. I will try to explain the problem in detail. I am working on a custom made board where an AC'97 rev 2.1 codec (TLV320AIC27) is connected to a SHARC processor (ADSP- 21065L)'s serial port and the serial port is in multi channel mode. My aim is to acquire the data at 8K sample rate. The following are the pin connec...

Hello, I'm trying to do some assembly stuff for the TS101 Tiger Sharc from ADI and I'm getting stuck. Here is my code: // need to do a multiplication "yfr11 = r6 * r5;; " // r6 fixed data, r5-floating data // now I want to left shift the result 20-bits to the left, logical left shift "yr7 += FDEP r11 by 0x140a;;" // logicall left shift 10-bits in yfr11 The problem is when I try to do ...

Hi All.. 1. As MATLAB uses the FFT approach computing the hilbert transform of the signal, is this approach suitable for real time implementation on a SHARC or TI DSP. ? 2. Can somebody point out some good references for real time implementation of Hilbert transform. Thanks Paul This message was sent using the Comp.DSP web interface on www.DSPRelated.com

Hello, I'm debugging some simple algorithms on ADSP-21161 Simulator and I need to simulate input data from A/C (audio stream, 400k samples). What's the simplest way to do it? Until now, I put some array into program or data memory (initilize using file.dat) but array length is limited by internal memory. I tried to change memory range but I get error: "Invalid memory range and/or width ...

Hi, I hope someone can help me with my problem. In my DSP program I want to change the wait states during the execution of my program, but I can't get the DSP to change the wait states. It appears the wait state settings are locked in at reset. Does anyone know if it is possible to change the wait states during execution, for example, change the wait states to read external memory and then ch...
