Starter DSP kit

Posted by stackleydevices at Tue Nov 29, 2011 3:55 pm

Hello Group -

Can someone recommend a starter DSP kit? I have seen the ones that TI is offering and not

sure which would be a good investment to get. What I want to do is to create basic adjustable

audio filters, for starters. Nothing hi-fi, using voice frequencies will be fine for now.

I have programmed in machine code, C++, Fortran and have a good hardware background and have also

worked with a lot of evaluation kits from different manufacturers. Thanks in advance everyone!

Joe Stack.

If you don't want to spend a lot of money on the big multi-media DSP dev kits, then consider anything with an ARM Cortex-M4 core.
The Freescale Kinetis KwikStik is very low-cost but features their K40 device. The M4 core provides a full suite of DSP instructions and the board has a microphone and audio out jack.
The STM32F4 Discovery board has an M4F core device which features floating point instruction hardware in addition to the DSP. It also has a microphone and audio out. It has a very small price tag as well.
Hope this helps.

Microchip has several solution from http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en534506 DSP based family up to simple 8 or 16 bit processor that may implement a FIR or IIR filter that if sampling frequency or number of taps is not too great may be done in a non DSP machine.
