Hi I am workin gon the customised board with ADSp 21160 and 25 MHz crystal on it. I am having problem in booting at higher frequency ie, at 100 Mhz(4:1 Clk cfg). At 2:1 the boot code is working fine. There is a slight variation in the boot code that is getting copied at the location in 3:1 clk cfg.=20 Consider this part of code that is getting copied at 2:1 in the mentioned lo...

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...

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 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'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, 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...
