I am a rookie at DSP. Anyone can offer me simulator for adsp 21xx and some e-books or tutorials?
Hi fakhry2002 I used it several years ago for starting a project with the adsp-21xx family and I found it very nice. The code in its examples can be readily modified (mainly DSPand SoundPort initialization) for your specific application. Probably a problem if you plan to start a project based in this family is that the AD1847 (the on-board ADC-
There is a lot specialazed uC for DSP tasks - for example adsp-21xx , TMS320C54XX. They calculate simple FIR filter with single instruction. Other big advantage of these DSP chips is that they have very good overflow handling algorithm and conseqently is "dificult" to lose information. Just look at the "adsp218X instruction set reference" (...)
For audio application, you may use some more powerfull (cheaper) DSP. Try Analog Devices adsp-21xx family (16bit fixed point). Some of this chips are really low power, if you plan to use them in battery powered devices.
for dsp programming of adsp 21xx enjoy
Hi You will find many DSP processors from TI and Analog. For low cost, you can choose a 16-bit fixed point processor from BLACKFIN-DSP family or adsp-21xx family. For mode details visit Analog Devices web site.
I hope nothing is fully free. You will find the tools all the DSPs of Analog Devices (SHARC, Tiger SHARC, BLACKFIN, adsp-21xx) are free for 90 days. You may visit the following site for downloading

Goertzel algorithm is a special kind of FFT algorithm that use for DTMF decoding. Here is a quick link about it You should also take a look at analog devices adsp-21xx Signal processing application handbook The printed
Hi Guys Does any one have a idea about how to do image resizing using fpga. I am suppose to work on a project for image rezising. We need to change the resolution of the image using fpga. does anyone has any material on this. Pls let me know thanks in advance tama I've seen this topic comes up so many times som
Hello Magnetra, if you would like to start with DSP I could suggest the Analog Devices 21xx series. Though it is an old architecture, it is easy to program both in C and assembly: I had the opportunity to work with adsp-2181 and personally I think that ADI assembly instruction set is the easiest to learn for a beginner, compared to Freescale (Mo
Who can give me schematics that shows how to connect more that two adsp-21160M sharing the external bus? For example, from h**p://www.bittware.com, there's a board named "HHPC" based on six adsp-21160; anyone have the schematic? Thanks in advance.
Look at analog devices design notes. Also, you can look at the document "adsp-218x DSP Hardware Reference". Regards
Can you compare adsp-2191 vs TMS320C5502? Which family are more perspective? What cool in both DSP`s?
Hi I need Test Drive Serial number for Mixed Signal visual DSP++3.0 for adsp-21992 device Thanks
try here there is a manual and some code for a whole load of experimetns for adsp 2181
Hi Sobakava, have a look first at this. It's the EZ-Kit Manual for 2191. Then for additional Information see the applicationnote side from AD: I am designing with 2106
Does anyone knows if there is C-Code for the realisation of a TCP/IP Stack on a adsp (Analog Devices DSP)? I need urgent helpt for that. I use adsp and want to integrate it in the DSP C-Code project and not use another yC for that. Thankx
I need hex file from ADDS-21xx-EZLITE or ADDS-2181-EZLITE development board. Thanks in advance!
Hi all, I am designing a DSP board with adsp-21161N. My idea was connecting 8ns SRAM to the external data port. The input clock should be 50MHz and the core frequency will be generated by PLL with factor x2 -> 100MHz. Then I had a look at the timing requirements of the DSP an found that for my configuration there is a maximum 5.5ns time for "a
1. What is the use of ON-Chip DM RAM and PM RAM? 2. How to interface external memory? 3. What is the relation between ON-Chip RAM Memory and External Memory? 4. How booting occurs in adsp? 5. How it is related to ON-Chip RAM? 6. Whatever program is written that is stored in EPROM then booting from ON-Chip RAM How? Pl clear this my doubts i
Can I program the JTAG port of adsp-2191 through the parallel port directly? I use Pin2 as TCK, Pin3 as TDI, Pin4 as TMS, Pin 11 as TDO. TRST* to 3.3v. EMU* unconnected. The wareform of TCK,TMS,TDI are right, but I can not find any signals on TDO using the oscillograph, why?
Hi, all ! I'm sure we have all faced this situation once : we have a simple idea, using a great-looking part, and as soon as we want to design a prototype board... ALL HELL BREAKS LOOSE :twisted: I'm in the process of designing a simple board for the purpose of evaluating the adsp-2191 in a very specific context. So specific in fact, that I
Hi The adsp-21535 is renamed as adsp-BF535 ( that is BlackFin DSP) Manual/Datasheet is easily available on Manufacturer's (Analog Device's) website. Search in the following site.
Try the second link under "Processor Manuals":

Hello, in processors with Harvard architecture Program Memory (PM) and Data Memory (DM) are separate and each one has a dedicated bus for IO operation to/from other functional units: this allow the parallel fetch from the 2 memory areas of Operand (from DM) and instructions/operand (from PM) in one clock cycle. This architecture is at the basi
