DSP single chip programming.

Postby Yurihalo » Wed Feb 22, 2012 2:20 pm

Hi evryone...I have a question on DSP processors. I searched in analog devices and texas instruments for DSP chip programmers but i could not find any such thing like a PIC programmer....if this is the case what is it that is used to load a program into the DSP???? I am so confused..... :?

If there are any links could you please post here so that you could save your time.. I know it is kinda troublesome for someone to write a whole description.... ..Thank You very Much..!!

Thank You very much for your reply.I really felt more enlightnd after that (really).had a tough time finding the answer through the web :yahoo: ..Sorry for any inconvenience i am causing but i've some questions that popped into my head with your answer...Does it mean that we can do this JTAG programming for a single chip after it has been soldered to the PCB with the allocation for a JTAG programming port to the single chip?  And does this mean that an evaluation board or a USB stick will be necessary for prototyping?( which is easier with a DIP package PIC and Breadboards).

I also heard that external memory should be used if the program code is too large. if so how is it that the dsp if programmed to fetch these instructions from the external memory(i.e. does the dsp have this capability? i really don't know)?

Thank You for your reply again.

Thank you very much for your reply.... I can now understand the picture of what's going on......I just have one final question to ask. Sorry for any inconvenience i am causing you again..... What i am actually trying to implement for my project is something like this:-

http://www.youtube.com/watch?v=Tg9G4Dfc ... re=related

It is the Korg wavedrum....

A smaller portable version is the Korg Wavedrum Mini

http://www.youtube.com/watch?v=GNXdqrOgghk

The Korg wavedrum Mini uses a 32 bit floating point SHARC processor that runs at 266Mhz... So if i were to use any PIC or dsPIC or the NXP1768...what would you recommend, from your experience.... so that i can actually approach close enough to one of the two?( My Project supervisor was like "You can do this, requires hard work ...")... I really dont need to have that much sound quality , but i only need the processing speed to perform fast calculations....

I really don't know whether i should be asking a question like this in the first place, but i feel more at home right here.....

Thank you again for the above replies...

(And terribly sorry if my question above sounds foolish :roll: )

No..no..no.. We as a set of technology enthusiasts enjoy exchanging ideas with you type of valuable future stars of technology world. So do not hesitate to ask any question here. We can't promise that we can give the answer. But we can promise that we will help you in our fullest capacity. We hope you guys will start doing the same here and get your friends to join with us as well.

My recommendation is dsPIC. 30F4011 is something that you can start looking at. Very powerful processor. I feel you will need to use a DAC as well. For real-time sound sample processing, I'm sure dsPIC will have enough power for you.

DSPs are very good for this. But as I said the only problem is the start up cost.

Another alternative that came to my mind. Have you thought about ARM ? You can buy a ARM Evaluation Module for less than LKR10K. This is also a good option.

You can also talk to the Aptinex representative here. They have quite a lot of experience with micros, FPGAs and DSPs.

Hope this helps!

Thank You very much for your reply ......I also will try to use the ARM in the design..... I also have an intention to use an FPGA and experiment with each of these or a combination(Cos my project supervisor advised me to consider FPGA as well....)...This topic has enlightened me on the path i should begin...Thank You again.... after the project i'll post what happened etc etc so that others can gain knowledge and will not make the mistakes i might make in the future...
