Dear all, ? I am working in a Digital Signal Processing Laboratory, and we use ADSP2189 and ADSP2191 DSP processors. We have implemented many digital algorithms by using ADSP2189 and DSM2180F3V successfully, and now I have switched to ADSP2191 and DSM2190F4V, but I ?have some problems with it as following: 1) To program the chip (DSM2190F4V) I need to build a *.hex file of o...

Hi, I need to use the 24k internal PM and DM of ADSP 2185 in FUSIV Vx170. Out of 24k, 8k is used as internal overlay. I am not aware of how the memory needs to be segregated for "live address space" and "run address space" and also need to how linking is done for more than one overlay page because the linker cannot place more than one symbol to the same address. thanks Navith...

Hi, I am using Blackfin ADSP-BF533 Processor for the audio system. I am new to DSP. Can you clarify the following queries? 1. Basically what Blackfin processor will do? I have to do noise cancellation and filtering? Will it do by inbuilt code? Or have to develop? 2. I have to burn the firmware into Blackfin? Or inbuilt code is there inside? 3. I studied that there is a code in the boot ...

Hello, I am a littele confused about the 21375 and the PWM-modul. On some pages at analog.com it is mentioned that there are 4 PWM outputs, but in def21375.h are no defines for the PWM control registers. Also the datasheet does not mention PWM at all. Are there PWM outputs built in the ADSP-21375 or not? Cheers, 0ger

Has anyone out there successfully interfaced a CF card (configured in True IDE Mode) with an Analog Devices' Blackfin BF548 processor via its ATAPI interface? Page 24-2 (p.318) in the "ATAPI Interface" chapter of the "ADSP-BF54x Blackfin Processor Hardware Reference" manual states: "Interface to compact flash (CF) configured in True-IDE mode". (This, to me, implies that this interface shou...

Dear all I?m new in this group and this is my first participation: I have a made home board using ADSP-21020 whit 512Kx48 program memory . I want to write my code in this memory whit an external EEPROM programer. The problem is that I have ldr file compiled for transfer using JTAG. I?m using Visual dsp3.5 and this is the only option I can choose. How can I do to transfor this LDR fi

Hi, my development project uses two DSPs: The ADSP-21375 and the ADSP-21369. For both of them I've the evaluation boards here on my desk. On both DSPs I want to send my own audio data to the codec therefore, I used the blockthrough examples but wihtout success. My output data are stored in two floating point arrays: fLeft and fRight. Now let's look into the processBlock()-routine. How do I hav...

Hello! We're using SPORT in multichannel autobuffer mode, SCLK and TFS/RFS are generated externally. After some special signal becomes high (let's call it RESET) SCLK/TFS/RFS are masked and SPORT should be disabled by DSP. When RESET becomes low SPORT needs to be reenabled. But after reenabling SPORT we have some corrupted data at DT. And (as we suppose) because RESET is async with DSP ...

Hello! We're using SPORT with external frame sync, external SCLK. SPxTCR = 0x85E1, dma descriptor mode (and even just simple writes to SPx_TX). We need an early sync, but independent of setting LATFS we get late sync. Why?

Hi, I am using ADSP-21262 for my project which is active noise control. Until now, I never get good result from my system, and I suspect that maybe its because of the default sampling rate that is too fast that doesn't give enough processing time for the algorithm. I've also try picking every n-th sample and filtering it with a low pass filter but still, I couldn't get the desired result. ...

Hello all; I recently tried to get EE-60 (218x UART.zip) running on the ADSP-2189M EZ-KIT Lite board with only partial luck. Does any one have a functional port of EE-60 over to the 2189M EZ-KIT? I'm running VisualDSP++3.5. Paul

I'm doing tests with hardware "ADSP-21262 EZ-KIT LITE" and the software as "Block Based TalkThru (C)". I put in the function "BlockProcess" my algorithm. But I see that output from the algorithm introduced me take effect only on 2 / 3 of the output signal. I also annoying peak (spurious effect) between a block and another. Can not understand where is the anomaly. Can you help Maurizio ...

Dear all Lately i have been working on adsp processors. But firstly i was never given a good idea why do we prefer adsp processors to traditional processors that is our computer cpu? I believe speed is never a factor because now a days we have multi thread processors capable of running complex video games. So how come a adsp processor is unique than a normal cpu of our computer?

Does anyone know if there are internal pull-up or pull-down resistors on the programmable flag pins (PF7..PF0) for the 218x series of processors? If so, are they configurable? How do I program them? What state are they (high or low)? I'm trying write a single software build to run on two different hardware architectures. Both use an ADSP-2188M. On one architecture, the software is suppos...

Hi friends ADSP 2181 and BF533 are not compatible. ADSP2181 is a 5V logic(TTL) while BF533 is a 3.3V logic device. If i need to connect ADSP2181 sport to BF533 sport is it enough if i use a voltage divider for level shifting? If not which level shifter IC is ideal in this case? I need to level shift all 5 signals on ADSP2181 sport i.e DT,DR,TFS,RFS,SCK.
