hi guys I'm using a ADSP-TS101 and need to implement a 10th order butterworth. I plan on using the irr function in the filter.h header file. For this function i need to know how many biquads stages there are...i assume 5? this is from the run time library description: The characteristics of the filter are dependent upon the filter coefficients and the number of stages. Each stage has five ...

Hello! Have you already tried the talk-through code examples provided by VisualDSP++ 4.0 for the ADSP-21364 EZKIT-Lite (...\Analog Devices\VisualDSP 4.0\213xx\EZ-KITs\ADSP-21364\Examples\ASM\Talkthru...)? By adding a simple loop in the main audio routine, the program bugs for a counter larger than 3500. This means that for a 48kHz application, the maximum delay is about 73ms !!! For insta...

Hello, I've implemented filtering on the ADSP-21364 with a sampling rate of 48kHz. I use both analog and SPDIF interfaces. And in each case, if I enter, for example, coefficients of a low-pass filter with a cutoff frequency of 500Hz, the signal is filtered by a low-pass filter with a cutoff frequency of 1000Hz. So everything seems to be as the processor would read and write samples at ...

Hi I would like to know how a floating point number is represented in DM if the width of the DM is configured for 16 bits and PM as 48 bits. I am using the EZLITE version for ADSP-21020/60 that is showing all floating point numbers as 32 bit. I am expecting the floating point numbers should use two consecutive addresses when the DM is configured as 16 bit. Any idea how it is r...

Hello: I'm a student at a university who is working on a project that involves implementing algorithms for stereo vision. The initial development will be done using Matlab and eventually the Matlab m code will be converted to C in order to run the algorithms on a ADSP Blackfin 561. Therefore I was wondering are there any tools that will generate C code from Matlab m code for the Blackfin D...
