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
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
