Hi all, I am working on ADSP-BF537 KIT. I am facing problem regarding profiling of my application. When I perform profiling on board (statistical profiling ) in debug mode , I am getting profiling report. But if I run my application in release mode , I get a blank report that probably suggests that no profiling could be done. I understand the limitation of statistical profiling , but my...

Hi, I am trying to calculate the number of cycle counts in my program for a particular section of the code. But I am not getting the total cycle count for some reason. I followed the instructions in the document VDSP++ 4.5 C/C++ compiler and library manual under section "measuring cycle counts". I am trying to use "Basic cycle counting facility". The part of the code I have written is as f...

Hi all I am working on playing a AAC decoded file on the speaker side on a ADSP board. To begin with , I have simply take a PCM buffer and am trying to play it on the speaker. I am using ping -pong buffer implementation wherein I am first writing data to buffer. Then through DMA , I am transferring this data to DAC which is connected to speaker. While this buffer is being played on spe...

Hi, First of all I am sorry if you are receiving multiple copies of this mail. I am trying to program and communicate with CODEC AD73311AR on SPORT0. I have programmed the CODEC to work at 1.024MHz SClock and 32KHZ sampling frequency. I am using I2 and I3 for initializing SPORT0. I am attaching the code for CODEC and SPORTs initialization function. It is clear from the code that I have buffers...

I'm a beginner when it comes to DSP but I need to learn how to implement basic filters on a DSP board. I'm using an ADSP-21369 EZ-Kit from Analog Devices. I understand how to generate coefficients using Matlab but how to I use these coefficients to filter my input signal. Can someone explain using either code or just an explanation. Any help will be greatly appreciated.

Hi Group, I am relatively a newbie to dsp and trying to implement some programs. Curretly I am using Tigersharc ADSP TS 201 EZ-Kit. One of my programs calculates cosine and sine of long double type values. I am wondering if there is a way to calculate sine and cosine of 0 to 1024 number of values ahead of time and store them in a vector and access it when the need arises. Couple of quest...

I am trying to port the melp code on ADSP-2188. First of all can anyone tell me where I can find the proper algoritm of melp (I want to understand it before porting it in and for conversion into assembly). Secondly I have the code from Texas instruments in C but I am not able to clearly see the interfaces and what initializations are required to port it. Where can I find a document or any inform...

Hi. In the ADSP-21262 datasheet (Rev B) is it stated that the TCK line (used for JTAG port) "must be asserted (pulsed low) after power-up or held low for proper operation of the ADSP-21262". However, in the ADSP-21262 EZ-KIT LITE schematic diagram it is pulled- up to mantain a high when you just run the DSP without JTAG intervention. Of course the TRST* must be held down after power-up bu...

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 ...
